Every now and then, the layout of this page gets messed up in my IE9 browser (but not Firefox) on Windows 7, Standards mode, 100% zoom: the content is shifted to the right and appears underneath the advertising. Other questions seem to be fine.
UPDATE: I think this is a bug in IE. I examined the page using Developer Tools, and it appears that even though the vote buttons and question are in adjacent
<td> cells, IE thinks there's an extra
<td> between them. You can see in the screenshot below how the blank space is precisely the width of the comments area.
