That is such an odd problem. I have 2 suggestions:
1 - First, see if the alt+tab is enabled. Do so by System>Preferences>Keyboard Shortcuts
and check some settings there.
2 - If suggestions #1 didn't work, try to create a new user and login with that user. If alt+tab works for that user, then most likely you've installed some application which messed the alt+tab settings (like a fancy 3d effects), so try disabling it/them.
