Ok, Yes i've searched, but haven't found an answer that solves this problem for me.

Anyways... if you visit http://www.xtremecast.org/nuke/index.php and click forums on the left(flash bar is not active yet), you'll notice that when the forums pop up that the tables spaz out and the forums also do not stretch properly. I've dug through every file i can find to try and resolve the issue but am obviously missing somethin very simple i'm guessing. If anybody could attempt to point me in the right direction I would very much appreciate it. Thanks in advance.

definitely looks like its within the the forum files. check index_body.tpl . but i cant be too sure.
