Auto type macro issue

Hello everyone, I'm having an issue with my RDM and autotype macros after my upgrade to Windows 10 (1607). My setup goes as follows, I have my credentials stored in a credentials object, the RDP session has my credentials configured, still when I connect (due to a Group Policy on the server side) the credentials are prompted anyways.

To automate this I have created an autotype macro (Events -> After Connect) which contains the following macro:

{Delay}$PASSWORD${Enter}

The delay is configured for 14 secs (14000 ms), and it used to work properly with my previous version of Windows 10. Now the behavior seems that when the popup to introduce the credentials appear, the macro is halted, since the notification in the right bottom corner that indicates the macro is in execution doesn't dissarpear until the popup is closed. Even if I close it after 15 or more seconds.

If I change the RDP session from "Embedded (tabbed)" to External, the macro works successfully. "Embedded (tabbed)" or "Undocked" will be useful to reproduce the issue, if changed to External, works perfectly.

Everything leads to think that with the new RDP version shipped with 1607 when the Windows Security appears RDM waits until it closes before continuing with the macro execution.

Hope this helps to get the issue resolved.

Thank you in advance,
Hernán
