Very nice, but...
I have a few more menu items than some people. (button prob.png)
I found where to adjust the height of the buttons, but of course, the roundish edges are cut off the bottom.
I'm using the text option, so the images are not a problem, although double lined menu items ("My Messages", for example) overlap.
Change the height of the buttons to around 35px, instead of 60px, (width is fine) and solve the overlapping text thing.
(or let me know where I screwed up with the CSS trying to solve it myself...hahaha)
Very nice otherwise.
