Css Flyout Categories Menu troubles

[fricy]

However, I still have two problems. There is no room between my flyout menu and the sidebox underneath that. This only occurs in FireFox, there is enough space when its displayed in IE. But I also have a light blue line at the bottom of my flyout menu. Any ideas?

I had the same issue with css flyout in firefox, but it worked flawlessly in IE.
After hunting for days for missing divs or errors in the code (being a new Zen hacker myself), I seem to have found a cure in the css:
Look for

div#nav-cat {float: left; width: 140px; margin: -1px 0 0 -1px;
background-color: #CE318C; font-weight:bold;}

and simply change to:

div#nav-cat {width: 140px; margin: -1px 0 0 -1px;
background-color: #CE318C; font-weight:bold;}

It worked for me. Can anyone explain to me why it works? :) DrByte?
