I have noticed an issue with the ComponentArt menu after I added a doctype to the expressTemplate.ascx to take IE8 out of quirks mode.
When I hover over the menu bar and a sub-menu pops up there seems to be 2-3 pixel gap between the main and popup menus.
Then if I move the mouse slowly to the sub-menu the pointer hits the gap and the sub-menu go away before the mouse enters it.
If I move the mouse quickly the sub-menu stays.
The menu works correctly on Firefox 3.5.5.
I have only seen this on IE 8, when NOT in compatibility mode, in compatibility mode the menu works as expected.
Has anyone else noticed this and is there a tweak to the menu to fix this?
