Is it just me or does PP2010 (x64) have problems with ATI cards and OpenGL?

I just bought PP2010 and installed it on my machine (Win 7 Ultimate x64 German, Core I7 920 @ 3.4Ghz, 12 GB DDR3-1066 RAM, PowerColor ATI Radeon HD 5870 1GB with Catalyst 10.2 drivers).

I unchecked the option to install 32bit files and used the traditional library setup (Runtime in the Poser folder).

Problem is that with the OpenGL Preview Renderer, whenever I move the mouse pointer over the actual display area, it goes black. When I move it back to anywhere else, it returns to properly displaying the scene...

Using SreeD instead, all is well. Also, I still have Poser 7 and 8 installed separately on this machine (both with latest service releases), and they can use OpenGL with no problem.

So, what did PPro2010 change in the way it handles OpenGL in contrast to earlier versions of Poser? Any hints or ideas how to get it running properly? °_°?

Cheers,
