Hmmm, in your "setup" for fad, try disabling OpenGL graphics, I've not seen this before, however I don't run XP (that is what you're running right?)
I've checked on my mom's who is running XP and her does not have this oddity, also you are running 1.21j correct?
hehehe, see what happens when you're watching the hockey game and forget to hit submit

glad to see someone has seen this before
