Are you guys using Chrome? I'm having a problem with how the main page is displayed and also having trouble with Facebook. I switched to IE and the problems go away.
What version are you running? 14.0.835.186 here. I run a prior version at work with no problems. After my reinstall, it's worse. Now it doesn't display some images.
fwiw, I had already made the firefox 7.0.1 update and speculated it might be the problem, but clearly it was in Rx house since only certain hyperlinks were affected
