Jerky movement in FF. Why? Any Solution?

Jerky movement in FF. Why? Any Solution?


I know Internet Explorer sucks. It causes a lot of unobvious obstacles
that one should always take by some trickery and dark magic. But now a
HUGE problem comes from our favorite and faithful companion - Firefox.
And the problem is that jerky animation during the movement of the
Dialog box. What's that? Doesn't it suck as much as a whole IE6? Why?
