There seems to have been a change to the website CSS or something within the past few days. I always have the font size bumped up a little on glitch.com since otherwise I can't read all the text, and this has always worked fine in the past. However looking at the forums today, the list of posts no longer sits nicely next to the sidebar, but is shunted underneath it.

If I reduce the font size, it looks normal again (but the text is too small for me to read comfortably).
This is with Firefox 10.0.2, OS X 10.6.2, and the NoSquint extension for increasing font size.
