Spry Horizontal Menu List Items crash IE6 browser

Question

****Update*****
Apparently, it was width:100%; set on each hover over
background color for the list items in our default stylesheet that
was causing IE6 to crash.
Menus are in working order in all browsers now!
We have integrated the Spry Horizontal Menu with a website,
and added custom styling to SpryMenuBarHorizontal.css. The menu
works in Mozilla, Safari, and IE7. However, in IE6, after hovering
over the navigation, the drop down menu appears, but, as soon as
you move your mouse into the drop down to select an item from the
list, IE6 crashes. Every time. Various Computers.
We have tried reverting to the original
SpryMenuBarHorizontal.css file, however, the same problem occurs.
We haven't made any changes to the original js file
(SpryMenuBar.js).
Has anyone ever experienced this issue?
Here is our customized CSS:

Answer 1

I am having the same problems in IE7. I'm using the latest
version of everything (Spry 1.6.1 and javascript file version 0.12)
and at first I was having the problem on my drop down menus
appearing horizontal with all the correct styles but when I changed
the rule ul.MenuBarHorizontal ul to position: relative; the drop
downs appear vertical now but I have no beige border around the
whole ul anymore and I'm getting white space inbetween list items.
http://www.wusf.usf.edu/Header_Nav_Footer_newStyleSheet.cfm
so if anyone has any advice I'd much appreciate it. Also i'm
using 1px width on my borders no decimals.
