AutoCAD Inventor :: Setting Background Color

Inventor uses a gradient-fill gray background for the 3D views.  This has many annoyances, such as parts of the image disappear at certain rotations because they render to the same color as the background.  More seriously, when I want to print the orthogonal 3D view, I get the gray background on the printout, which looks profoundly ugly, and obscures some of the critical information I want to see. 

Is there a way to either (a) change the background to something other than gray-gradient?  (I'd settle for something like light-blue-gradient, for example) and (b) tell the print command to not print the gray background (but if I change it to solid white, this would solve the problem)
