Submenu doesn't increase height when items wrap, making them almost invisible

[MC_incubus]

The second level menu has a set CSS height, which means that when the browser window is narrow, the items wrap, but the size of the bar doesn't increase, which means you have #ffffff text on #a9a9a9 background... white on light grey.

My patch solves this by eliminating the set height, and the remaining changes are to make sure highlighted or active tabs are big enough to reach the grey area and create that tabs look. I have tested in Firefox 1.0, Mozilla 1.7.5, IE 6, and Opera 7.23, all on Windows.
