Flickering Edit Windows

I am having a problem with Blender that came up recently and seems to be getting worse. Initially what was happening was that when I had a model in UV Face Select Mode and moved the mouse around outside that frame it would flicker between normal and black and red like so:

Now it is getting worse. When ever I am in edit mode and try to resize an object all of the frames in edit mode flicker something awful.

Does anyone have any idea what I can do?

Possibly useful info:
I am running WinXP ad have a GeForce 8800 GTS

EDIT: It also seems to do the flickering thing whenever I mouse over any button on the entire Blender screen.

Does it still happen when you delete the Subsurf Modifier? If so it sounds like a Driver or Hardware Acelleration settings on your video card.


I just ran a test and it still flickers when the subsurf modifiers are absent.
