Main Page Text Is Intirely Bold

Ok, I have been having trouble with the sidebar dropping when viewed in IE.
I figured out that if it happend, I could delete the post and redo it and the problem was eliminated, except for today.

I deleted and entered the same post several times but the side bar kept dropping.

Then I noticed that part of the main pages other posts had suddenly changed to all bold text.

Can anyone help?
