CSS? Safari?

I am having some trouble with my template for this site... see between Member of: and Friends: ? the space is a different size... I have checked the syntax 4 times, and everything is identical down the whole list... all of the headings are h6, and all of the lists of links are enclosed in ul, and all of the individual items are enclosed in li. Nothing changes on that one, but for some reason it is slightly smaller, and closer to the previous list. AGGH!
(I have added 2 blank p's and a br to get it as wide as it is... adding more doesn't do anything) DOUBLE AGGH!

Maybe it is a Safari Bug?
