I'm using Windows 7 64-bit Home Premium locally and Windows 7 Enterprise remotely via Remote Desktop. The RD window is full screen. Sometimes, when I press Alt-Tab, it is processed by both the remote machine and my local machine. The result is that I get switched to another local window and when I switch back to the RD window, it has switched to another window as well.
This only happens sometimes. If I press Alt-Tab again after switching back to the RD window, it will work correctly. But if I wait about 10 seconds and then try again, the problem happens again.
My local Windows 7 is not patched to SP1, nor is the remote Windows 7.
