It looks like this didn't fix this problem. I'm not sure if it's a  
rendering problem in in g.pnmcomp or something in the wxPython  
rendering engine. Whenever more than 2-3 maps are overlayed, only the  
top couple are displayed. The lower ones become completely obscured by  
the upper ones--or are not rendered at all. The overlay flag is  
checked for rasters and there should be no overlay issues with grids,  
or vector lines/points anyway.
