2011 file menu freeze

I installed 2011 on Monday and things were going along pretty well until this morning.

Now when I click the "file" menu, my screen freezes. When it's frozen I can't move the mouse or do anything. Then after 5-10 seconds I can select

save, open or whatever but solidworks has to think for a bit before it lets me select a command from the menu.

Has anyone else had this problem? I am running a HPZ400 with 3GB DDR3 @531MHz on xp32bit with an NVIDIA Quadro FX 1800.

All other menus are working fine and I never had this problem with SW2010.
