I installed the click-show-hide menu, edited the stylesheet how it needs to be, and it messes my page up in IE.

I have tested this by uninstalling and reinstalling the mod.

I set up a test shop HERE. It is a fresh install with only the click-show-hide mod installed. I didn't install all my modified files (for the navigation links, etc..) so just ignore all the undefined constants.

The issues are:
1)The menu is pushing way to the right.

2) If you click on a link that has nothing in the centerColumn, such as the 'specials' link, the right sidebox moves way to the left. I could fix this by setting a fixed width for the centerColumn in the stylesheet, but it shouldn't be doing this in the first place.
