In Firefox my subcategory products are in two columns but in IE they are in a single column. I prefer them to be in two (or three) columns. I can't figure out why it is different in IE. Any help is greatly appreciated.

Here is the page:

Again if you view it in firefox it shows two columns but then in IE it shows only one
