I've got a problem with IE 7 RC 1 and my web site. I open my web site in a tab and then open another tab and go anywhere (Yahoo or Google). I sit on that tab for a while and then go back to my web site. The table expands and looks awful.
I've included the link to the one of the pages with the problem.
Look at the source and see if you can figure it out.
