Answer 1

bit of excess functionality, but this article explains why you cant do that dynamically and provides the easiest solution... http://www.twistermc.com/36764/shrink-facebook-tabs/ The answer is simple: Shrink it really small, then after a pause use AutoGrow to make it the correct size... Alice in Wonderland style.

• I say easiest because from a dev and user point of view this slows things down by about 1/4 second, and the user gets a tiny flash of the scrollbars...
