Accordion 1.7.2 shrinking ineffectively in IE8

Accordion 1.7.2 shrinking ineffectively in IE8

Hey all,
I'm new to jQuery, and as such I turned to the internet for help. Googling for information on the Accordion gives me examples, but none seem to match what is going on with ours. I have a accordion set up in this fashion.


Upon entering the site you can see a list.

Menu1

Menu2

Menu3


Expanding that lis will give you the submenus. All sub menus work correctly; so No need for me to worry about them; It also works and appears like it is supposed to on Page load in IE and all around in FireFox.

What happens in IE8 when you click Menu3, Menu 1 & 2 are intended to collapse, but retain a spacer between each div tag. It will look like:
Menu1
Menu2

Menu3

an Interactive site is live on our test server here.

It essentially ends up being bunched back up until you mouseover a link on the page and it reloads.

Any help would be appreciated.
