While editing materials I closed the PhotoWorks preview window (by clicking on the "X" close button). Now no matter what I do the window won't return. Normally it just reappears when you click the "Material" or "Scene" button, etc. "Display Preview Window" is still checked in PhotoWorks Options. Is there some other place to turn the window back on? I've even tried exiting from SolidWorks and rebooting, but no luck. - Chris
