I would update the drivers if I could.  Avid will only work with an older legacy driver.  If try to open Avid with the updated driver, all I get is an error message.  As I make my living as a video editor, I can't afford to lose my editor to make Poser work correctly.  Buying another powerful computer (I do render heavy animation) just for Poser just isn't an option.  The fact that After Effects, Photoshop, Blender, and Vue all run fine on my system with no problems makes me wonder if the driver is the culprit.  As I said, if it is the driver, then my Poser days are over.  A bummer since I just shelled out a bundle for PoserPro 2012, and really liked it when it was running great on Vista.  My Vista system also required an older legacy video driver to run my old Avid system.  No problems then.  If Poser ran fine with even an older video driver than I have now, it may be the Poser - Windows 7 combo that is fouling things up.

Thanks everyone for the help.
