Which version of Firefox? Which version of IE? Please be specific.

If I have set color to be black if the author stylesheet does not define
one, then I'll have black on black.
If you submit your stylesheet to the CSS validator, you'll get a
warning, precisely for such reasons.

Is your menu still working in 800x600 scr. res.?

One recommendation/advice when designing stylesheet is to set width and
height using the same unit, at least the same type of unit (absolute or
relative. You avoid some type of rendering problems that way. At the
very least, use absolute or relative unit for the dimension of a page
division, not both mixed up.

CSS 1 and CSS 2.x specifications require that non-zero values must be
specified with a length unit; otherwise, the css declaration will be
ignored. Mozilla-based browsers, MSIE 6+, Opera 7+ and other W3C
standards-compliant browsers enforce such handling of parsing error.
CSS 1 Forward-compatible parsing
http://www.w3.org/TR/REC-CSS1#forward-compatible-parsing
CSS 2.1 Rules for handling parsing errors
http://www.w3.org/TR/CSS21/syndata.html#parsing-errors
An example is well given by your own stylesheet: sometimes, you use em,
sometimes you use px. A machine reading your stylesheet would not be
able to assume what unit you use for font-size.

Where is ul.admin in your code?

If Gigs is not a link, then don't use an href for it. You have to
consider cases where javascript support is disabled or inexistent. Your
markup code and css must degrade as gracefully as possible. Here, I'm
sure the accessibility of your menu could be improved.

Same thing here: if Bio is not a real link, then do not define it as a
link. The menu could still be expandable on a click event ... without
having Bio as a link.

Where is the javascript/DHTML triggering the pulldown of the menu?
Can you please from now on only post an url, not code?
