I'm not sure if this should go here or the support forum, but I just found a bug in the INove theme.
When viewing posts by category, 10 most recent posts are displayed on each page. But if those posts are really long, the main column got truncated after several posts, and the rest are pushed aside to the toolbar/widget area, which doesn't have enough width.
DOM structure inspection reveals that the DIVs of the pushed aside posts got inserted outside of the #main DIV.
This happens on both IE 8 and Firefox 3.6.
