My Windows XP SP2 has been annoying me a lot recently. Basically everytime
when I watch a movie with "maximised" Windows Media Player 10, or RealPlayer
10, or Media Player Classic 6.4 then at random times the player would
"restore" the window size, as if some other program spawned or received a
notification. But guess what, there is no other apparent window or program
to be seen. I make sure my MSN, Virus Scanner, etc are all switched off. But
every so often (regularly), my maximised video player would "restore"
itself. Is it Windows Update in background? I don't know, but what would be
handy would be a "forced" maximise mode. And what gives a program privilege
to "restore" some other window program?

Has anyone experienced this too?
