I just upgraded to 3.2 yesterday and I'm now experiencing weirdness with my Alt-Tab. When running full screen, Alt-Tab engagues the host's windows, not the virtual machine's windows. I have to Alt-Tab to the host window and once selected I can Alt-Tab within it's windows, but only until I give focus to one of the windows. For instance, if I click on an open terminal window then Alt-Tab will show the host windows until I select the VM window again. This just started happening with the new version.
My setup, Windows 7 host, Windows 7 virtual, running 2 virtual monitors, running guest add-ons.
Anyone else experiencing this?
