Keywords: Windows floating menu items left screen dwm
Sometimes, under Windows, a floating menu item gets left on the screen. It's possible it may have something to do with Chrome. The only way to get rid of it is to reboot the machine. (Or maybe logging out works, I don't think I ever tried.) Well, obviously neither of those options is particularly attractive, but it turns out there is another. better option. Killing the dwm.exe process fixes the problem far more satisfactorily.
dwm.exe is the Desktop Window Manager which looks after thiings such as the 3D effects and transparencies. When it is killed it simply restarts itself.
