I am using Poser 5. For some reason, the Background Color will not "stick" -- I am stuck with the default gray background. I have tried changing the background color using both the Background Color button next to the main character window, and using the Materials room, but no matter how many times I change it, it immediately reverts back to the default gray. The odd thing is, if I open a saved scene which has a different-colored background, it keeps the background it was saved with. I am baffled. Is there some setting I have inadvertently toggled?
