good design, but you have some details to fix:
1- best view in IE is obsolete... try to be W3C/XHTML compliant, and you will have less problems in your design... btw, the original style you modified was basically cross-browser compliant... you just edited some details that make trouble...
2- use font colors, because the default blue is ugly on your style... brown-like would be better... to fit your skin.(the one from your site...).. lol
that's it..
