jQuery slide menu problem

[Bill Fergusson]

1) Script Title: jQuery Multi Level CSS Menu #2

2) Script URL (on DD): http://www.dynamicdrive.com/style/cs...el_css_menu_2/

3) Describe problem: With IE7 and IE8, 2nd level sub menu items do not display if jQuery version used is 1.5.1; If jQuery v1.4 is used, if mouse over sub menu item, then top menu item, then sub menu item, the right arrows are not visible; but all is OK with jQuery 1.2.6.
Note: All other modern browsers do not exhibit this problem.

4) UPDATE NOTE - I have found that if .toggle() is used instead of .slideDown and .slideUp, both problems described do not exist with jQuery 1.5.1, EXCEPT that if you use .toggle('slow'), then sub-sub menu items do not show.
