I am using 3 monitors with Windows 7 Home Premium; until recently, it was easy to manage them (ALT left arrow would move a monitor to take over half the screen on the left, pressing it again would move it to the other window, and so on, ALT right arrow would make another window take the right of the screen). Sort of the Windows 7 "shake" feature but working in the middle monitor. Now the feature comes and goes. It either works or it don't - pressing the ALT key may result in the Firefox menu being displayed (i.e. File, Edit View, History etc). This may be an issue with the new office update for Word or it may be a setting hidden somewhere that got changed accidentally. Any ideas?
