I really like Windows 7's Alt+Tab switcher, however, it has started to revert back to the XP version. This website
shows how the problem can be reproduced, but I am not accidentally using that method. Restarting my computer will reset back to the intended Windows 7 switcher, and some time later, when I go to use Alt+Tab, it will simply be in the XP version.
Any ideas about what could be causing this? Or even a way to revert back without having to restart? Thanks in advance for any help.
