Please take a look at this website in Fireforx and Safari, then IE8.

When you click from the main Navigation on the left, its a fairly smooth fadeIn/fadeOut transition between categories (pages) in Firefox and Safari. But in IE8 the transition is abrupt, almost like I am using 'hide' and 'show' instead of fadeIn/Out.

Anyone know why it's doing this and/or how to fix it?

Thanks for any help!

(this is still a work in progress)
