First - I read a few forum contributions, but do not find one for my wishes / problems.
I use the RDM 126.96.36.199 on Mac 10.9.5 with the undocked rdp window for my systems (xp, win7, win8, w2003, w2008 ...) and I often switch between this windows.
If I use the CMD+TAB always my windows start menu is open. If I want to hide the rdp window with CMD+H nothing happens. If I want to close the window with CMD + W it send a CTRL+S (e.g. in my app it is used for search).
Some times if I use one of the keyboard keys I have trouble in the rdp window (a other control key is in fixed pressed mode).
A other example: I stay in a rdp undocked window - open the RDP About window and want to close it with CMD+W ... nothing happens.
I do not want to complain, I love the RDM on Mac - I only want to know if I am to stupid :-)
Thank you for submitting these issues.
We will take a look at them and fix everything we can.
