I just installed PoserPro2010 on a new Windows 7 OS running a brand new Visiontek ATI Radeon 5750 graphics card.  OpenGL looks fine...but when I place my cursor over the Poser work window, the image goes all black and the character gets blocky and it's just screwy.  Move the character or the mouse and it goes back to normal preview and at all other times it's normal looking.  Switch to Sree3D...and no problem at all.  I have checked and I have the most up-to-date driver for the card...released December 2009 when the card was released...and I've got DirectX 11 installed.  It's weird...I didn't have this trouble at all with the old Vista system.  Strangely, this issue is occurring in both 32 and 64 bit versions. 

Does anybody have any suggestions on this?  I couldn't find any similiar problems posted.  Thanks.
