I found the solution to the problem. It seems that if you are running the PMetrics plugin and have the code embedded in your footer then you run into the stack overflow. I took out the stuff in the footer and viola fixed.
I only recently started having this issue. I checked the descripting buttons as suggested. In FF everything looks and acts fine, but in IE…not so lucky. The left sidebar is FUBAR. Anyway, any help would be appreciated.

Looks, good, that header is a beautiful picture. I also like the three columns, helps organize info a little better!
your theme looks great, i had never been on your site until today, but your little girl is adorable, mine is 2 months old now. Really do like your theme, you inspired me to make my own.
