JQuery UI accordion with IE7, FF3 funkiness


Hi all, new to jQuery. Trying get Accordion to work proplerly in IE
and FF.
IE7, the content tabs get consecutively smaller on each mouse over
eventually shrinking to nothing!
In FF, the content boxes resize in width and then return to normal
size by a few pixels making the whole container wiggle on animation.
I have no idea what is going on.
Any pointers?
