I posted on this yesterday, without any response yet.
However, I “downgraded” to v. 2.0.9 and that has fixed that problem, although it’s not the longterm solution I’m hoping for.
From a desktop publishing point of view, it looks like the 7px on the bottom is “nudging” 2 lines of text instead of just one. If the ad or your 7px measurement were slightly smaller, I think you would get the result you want.
Alternatively, increase the line height in your body text slightly.
I *think* that would get you the appearance you want.
HTH.
I’ve sometimes had problems like this in Firefox, but not in IE7 (sadly). Maybe try switching browsers?
