Comment 29 for bug 733393

I can confirm the fix at:

http://abz89.wordpress.com/2011/05/02/how-to-fix-emerald-in-ubuntu-11-04

works fine.

I found I had to use the emerald theme manager, under the 'Frame/Shadows' tab, to nudge the values of the shadow radius (to get rid of bright white borders) and the size of the left & right frame borders (to reclaim the left/right window resize handles).

Other than that, the above fix is working good here.
Using a nVidia GT250 card, and Ubuntu Classic.
