Copy/Paste issues with 11.6.x

Do you have a clipboard manager installed on your PC?

We've changed the way we use the clipboard to make it more secure and allow for copy once, paste two (Copy the credentials, paste username, paste password) all without having to copy twice)

We have a system option where you can revert to the legacy copy/paste method. File -> Options -> General (section) -> Clipboard (sub-section) -> Clipboard copy method -> set it to "Legacy". This should resolve the issue.

If you do have a clipboard manager please let us know which one you have. We can investigate how to make it work with it.

Best regards,

Thanks for the response - the workaround fixed it. I don't have any clipboard managers, but who knows if any of my other utilities could somehow me jumping in. When I have some time, I'll perform a full uninstall of RDM and see if a fresh install helps - been a long time users with many updates/betas under my belt. I'll respond with the results hopefully over the next few days.

Thanks!
Tom

Thank you for the update.

For your information. The new copy method is considered "more secure" as it only allows for a single paste to be done.

With legacy you can paste the username or password multiple times until RDM clears it (10 seconds I believe). With the new method we only allow for a single paste. This why I'm suspecting a clipboard manager or other application of some sort that is peeking at the clipboard value and taking the one and only paste so that when you go to paste the clipboard is empty.


If you try the "Copy username & password"? What happens when you paste & paste again? Both username & password are pasted? Password only? Empty?
Note: the new "Copy username & password" action must use the enhance clipboard (regardless of the system option) and may not work properly in your case but might help in solving the issue.

Best regards,

If I try "copy username & password" and try to paste something, it's empty.

So I started exiting out of all the applications in my system tray and would try the process of copy/paste each time. When I stopped Citrix GotoAssist, everything started working. Turn it back on, no copy/pasta, exit out, works like a charm. The version I have installed is 2.7 build 1092. I saw nothing in the preference and settings that showed anything about clipboard access. I very seldom use GotoAssist, so I'll just stop it from starting up with the computer. If there is anything I can do to help you figure anything out let me know.

Tom,

Great investigative work. It's kind of alarming knowing that GotoAssist monitors the system clipboard activity like that. Not sure why they would be doing this.

The way we work with the "Paste once (secure)" mode is we notify the clipboard that we have value available to be pasted. Once someone asks for it we supply the value and block any other further requests. It's more secure since we minimize the total time the information is in memory unencrypted. In the case of GotoAssist it must be requesting the clipboard content before you have a chance to paste it elsewhere.

We will investigate what we can do but I'm not confident we can get it working while GotoAssist is running. We would need to block it from looking at the clipboard.

We will add GotoAssist to our list of software that may cause clipboard issues.

Best regards,

It scared me as well, sending a copy of my clipboard to the mother ship! :)
Thanks for the assist getting me to the right spot to find it. As always, you guys do a great job!

Hello everyone,
I have the same issue as Tommmucha, If I try "copy username & password" and try to paste something,it's empty!:(!! If I use the single function, so Copy Username or Copy password its work!, the combination not.....

I don't use GotoAssist or other program that use some clipboard manager... please find a fix for this !!!


If you need logs or something please let me know.

@Supporto tlco - What is the value of "Clipboard copy method" (File -> Options -> General (section) -> Clipboard (sub-section) -> Clipboard copy method)?

I'm assuming you are already set to "Legacy" since the "Copy Username" and "Copy Password" are working but "Copy Username & Password" is not. The setting only affects the single not the double since we must use the "Paste once (secure)" to be able to support the double paste.

As for logs it won't help since it's out of our control. The only thing I can think of is if we could somehow list the applications that are monitoring/reading from the clipboard. I have not yet researched the Windows API on this so no clue if it's even possible.

We might also need to add a RDM option to hide the "Copy Username & Password" actions (button/menu item) on systems that for reasons out of our control the double paste is not possible. Why have a useless button in the UI in this case?

Thank you for the feedback. We will investigate

Best regards,

Hello again,

I'm doing some test and investigation and I noticed that if I click on Copy Username&Password work only inside the connection, instead if I try to click again and try to paste in a Notepad or somewhere else not work!

Is possible to avoid this kind of "security" behavior ? I try to put the Legacy copy/paste method. File -> Options -> General (section) -> Clipboard (sub-section) -> Clipboard copy method -> set it to "Legacy".but no way.

thanks in advance

That is good news. It works but it might simply be a question of fine-tuning the delay at which we manipulate the clipboard (default is 10ms).

I will expose a system option for the clipboard delay in the next release so that you can try setting it to something somewhat longer (20ms? 50ms? 100ms?).

Keep in mind, too long and you will paste the username multiple times to slow and you can't paste anything at all.

We will see if that resolves it in your case. May also help @tommucha use case with GotoAssist.

Best regards,

I don't get how Copy / Paste Usernames & passwords is supposed to work. When I set the Clipboard option to Paste Once (secure) and Dual Action, the Paste option in the toolbar is always greyed-out. If I right-click while in a Username field, I can select Paste and it pastes the Username. But then I have to select Paste a second time with the cursor in the Password field. Shouldn't it paste both at once. And shouldn't the Paste option in the Session -> Clipboard context menu change (and save) the Username and Password for the session.

If I set the Clipboard Option to Single Action, then the Copy Username & Password command is not present in the toolbar and the Session context menu. I presume this is correct. But I copy a password and the Paste command is present when the cursor is in the Username field. Shouldn't the Paste command be greyed-out if you are Pasting into the wrong field.

@Sue Parker - What session type are you trying to paste into? I'm not sure I understand the context and your question. Could you post a screen shot of the behavior.

Best regards,

I am having the same problem when TeamViewer is running on my machine.

@Matt - If you close TeamViewer all works as expected? Could you try to increase the File -> Options -> General -> Clipboard -> Clipboard secure copy delay?

Try something high like 3000ms (just as a test). This will cause RDM to leave the copy buffer intact for 3 seconds from the first past request. Assuming that TeamViewer must be doing to the first request. This would give you the remaining 2.x seconds to perform your own paste (say in a login form). The caveat here is you must now wait for the remaining milliseconds to elapse prior to attempting to paste the password. Example if open Notepad and keep CTRL+V pressed you will see your username pasted over and over again for the next 2.x seconds then the password for 3 seconds.

Like I said, this isn't ideal but it would give us an idea if TeamViewer is in fact looking at the clipboard buffer.

Please let me know how your system reacts.

Best regards,

Here is a screen shot of some suggestions for the Clipboard feature. None of them deal-killers, but without any explicit Help on how to actually do the Paste operation, my imagination got the better of me.

@Sue - Thank you for the screen shot.

The "Paste" on the top ribbon bar is a "Paste Session", for it to be active you need to copy an entire session (using the "Copy" action or right-click on a session -> Clipboard -> Copy) http://help.remotedesktopmanager.com/index.html?home_clipboard.htm

As for the Copy Username & Password, Copy Username & Copy Password these actions primary purpose is to be then pasted into third party apps that don't support automation (VPN, in-house custom softwaree, web page...). You can of course use them to paste them back into an RDM sessiosn but instead I would suggest you link both sessions to a credential. You can follow this link for more information: http://help.remotedesktopmanager.com/index.html?bestpractices_usecredentials.htm

As for disabling paste when the copy buffer contains a password and a user is pasting into a username field suggestions. Unfortunately the underlying clipboard subsystem doesn't allow for this behavior. There is not much we can do.
