What I have been told, is that this happens to some people. The only recommendation I was given, at this point, is to try another browser.
Mozilla and Opera were both mentioned by name. I suppose Firefox would be another option as well.
Personally, I'm an Opera user, except for when I'm at work (like right now), and I recommend it highly.
It has a lot of nice features not found in IE (the selective popup blocker might be my favorite).
