I have a black blinking line for facebook

[pcoggins]

Recently, I have a 2" wide 6" long black blinking line when I get on facebook. there is nothing else. It only happens on my Lifebook, Fujitsu. I have run a spybot and cleared all history. any suggestions? it does not do that on my pc.

What browser IE9, by chance ? Click tools, compatibility View, see if that helps.
