Weird behaviour with IE

Hi list. I know this may be a bit out of topic, but I've decided to try. This website I'm maintaining opens just fine in firefox, and loads everything. However, the same doesn't happen in IE, since the status bar reads "1 item(s) remaining" on most of the pages. That issue raises another problem, because I really need that onLoad event to be fired ;) Has anyone had problems like this? What did you do to solve them? Thanks in advance, André
