blogging problem

Ah,,... I'm having problems with my blog now. It does not load well in Internet Explorer. The right side navigation bar seems to be loading right at the bottom of all the postings. I can't find the error anywhere. Spent few hours re-organizing my links and all. I even reset the template back to default but nothing is working. I've no idea what is causing this bloody error. Both Netscape and FireFox browsers seems to be coping with the error. Darn it.
