Nope. But, then, I was trying under OmniWeb.

It seems that IE is the only one that does it wrong.

These people seem to have come to the same conclusion.

Wow. Try resizing the IE window vertically. Making it smaller causes the 100% row to remain the same size. Making it larger causes the 100% row to grow to always be too big. I'd say that this is a huge bug in IE. Period. That doesn't help you, since most of your users will have the same bug, but it seems to be the case.
