This is very strange. When I load the example page in IE7 with Vista, the menu system hangs and runs very slow. It seems that while the menu code is being processed it is conflicting with other events going on (i.e. flash). This only seems to happen with IE7 and vista. I have two other machines and the page runs fine in IE7 running on XP and Firefox on both.
I'm thinking the problem may be specific to my system but I'm not sure and I need IE7 to display properly or testing the site is useless.
Hope someone can help... Thanks,
