This is a serious issue seen in Firefox 2.0.0.11 and I.E. v. 7 (and
previous versions of both Firefox and I.E.) for XP, Vista, and Mac,
although the issue tested isn't seen on every version of Firefox and
I.E. for all three OS's.
The problem: the links for the sub-menu will begin to overlap on their
surrounding links after clicking on the particular link. This will
continue until the link is fully over the surrounding link.
The b classes are there for a border around the menu.
CSS:
#container .menu {
font-weight: bold;
