I take it back, maximizer is having trouble on all 3 machines, it seems to have the best chance of working if it is a cold boot, a hibernate and it doesn't work.

I get a "MMDEVAPI device..." showing up in taskbar, if that happens wow never gets maximized and the keystrokes never make it to wow. usually have to kill wow from the task manager. I guess I'll try to uninstall SP1.
