Black Screen on Resize

Hi NG,
I have the following problem: I play Wolfenstein: Enemy Territory and
use the ET:Minimizer to minimize the ET-Game and resize it again with
ALT-Z. Minimizing works fine, but resizing ends in a black screen. The
game hasn't crashed, because I can still hear the sound of the game. But
as I don't see anything I have to close it anyway. The problem has
occured since I've used the Catalyst 4.11 driver for my Radeon 9800. Now
I'm using the Catalyst 4.12 BETA 2. For a short period of time I could
play the game without this handicap with 4.12 Beta 2, with 4.12 Final
I've always got this problem. After deinstalling 4.12 Final and
reinstalling 4.12 Beta 2 I've now always got the described problem.

Would be nice if somebody of you could help me...

Thanks in advance
