Definitely not. I can view the pixmap file fine with 'xv'. Not to mention
browsing the web or viewing images certainly shows more than 256 colors.

Problem occurs when no other apps are even open.

the 'nodither' option makes it look somewhat better, but it's still displayed with
very few colors. When I remove 'nodither' it looks as it had when I used the
MenuFace parameter of MenuStyle. I'll look more into these other options you
mentioned
