Product Text Moving over image after about 1 minute

I have this problem with my site where when you first go to the site the page looks fine with the product image on the left and the text in the middle of the page.

However after about a minute of being on the page the text moves left over top of the product image and which makes it unreadable. If I press the refresh button all returns to the correct layout for another minute.

I am stumped as to what could be causing this.

Here is a product url for my site.
http://montgomeryroad.com/store/index.php?main_page=product_info&products_id=87

Please help.

Many thanks in advance.

Where did you get your template? If you switch to the Classic temporarily does the bad behavior stop?

Is this perhaps fixed? I cannot get the text to creep along in either IE or FireFox ... :unsure:

It was a old template monster template that I modified. When switching back to the classic template the problem goes away. So that seems to suggest that it is caused by my template, just dont know where to start looking.
