Thanks Mihai,

Your fix certainly makes it a lot better, but there is still a 3px overlap when using IE - http://dev.whiteyork.com/concepts/marcus - click on the Events menu. I haven't tested the new fix with Safari yet, but will be able to do so tomorrow.

If you look at the source, you can see that the menu and the specified containing div are nested within 2 other div's. This is necessary for layout of other content, but if I remove these surrounding div's, then the menu displays perfectly!

As you will be able to see, for the surrounding divs, the styles are as follows:

#bodyborder { width:760px; border:1px solid #1C2E5A; }
#bodyholder { width:758px; border:1px solid #000000; background:#0D132E; }

If I remove the styles from both of the div's, then the menu will align itself perfectly. If either of the styles are applied to the surrounding div's, then there is a 2-3px overlap (when also using your fix).

thanks again,
Marcus.
