I had very odd behavior with the pop out "side regions" in Internet Explorer 8. I had put one block in the left region (Navigation menu) and another block in the right region (Primary Links). When clicking the left region popout it appeared to expand the width (scrollbar visible on bottom of browser area), etc.
Not on Windows at the moment otherwise I'd post a screenshot.
