During the process of building a website, I encountered an unusual issue with Internet Explorer and our CSS menu system. The top-tier a tag in the menu doesn't seem to have the same clickable area as Firefox and Chrome provide. This is because the a tag isn't directly adjacent to the sibling ul element. When hovering over the a tag, the ul appears but disappears when trying to move towards it because IE does not recognize that the mouse is still hovering over the li element containing the a tag.
You can see an example of this issue on the following page: Problem with IE and CSS menu
I am looking for a solution that will work in IE version 8 and above.
