When combined with Ctrl or Alt: RDP Shift Key Gets Stuck (via: davidbond.net)

When using Windows RDP you have the risk of a Shift key getting stuck.

This happens when press Ctrl and Shift. Make sure you release Shift first, otherwise Shift gets stuck.

Same with Alt and Shift: you have to release the Shift key first.

This is not a problem when using the OS X Remote Desktop application 8.x from Microsoft: only the Windows MSTSC.exe applications included in Windows 7 and higher suffer from this when you connect to Windows 7 and higher (including connecting from Windows to Windows Server and from Windows Server to Windows).

It does not happen with the MSTSC.exe in Windows 2000/XP and Windows Server 2003/2003 R2.

Results

Here are the important results:

• Press Shift and Control (either order) -> Release Shift -> Release Control: Normal state
• Press Shift and Control (either order) -> Release Control -> Release Shift: Problem state 

Conclusion

RDP has a bug whereby the shift state incorrectly remains in the “pressed” state if, after pressing Shift+Control, the Control key is released first.

You have described the exact same problem that I am having, only in my case it’s with RDP between two Win7 machines. […]

I have been using RDP for years without problems, until about 2 or 3 weeks ago when it suddenly starting going wrong.

Too bad the connect issue requires logon: I have no idea if this is ever going to be fixed.
