Thank you!
I admit that is it exactly. I knew it was a base for other desktop installs, but when i saw/ read it was fluxbox i was all set to change theme, edit menu, edit startup, and download some programs. I should have realized xorg is incomplete by definition, even for fluxbox.
At any rate, i am now on my way. I thank the Siduction team for including FB as a stand-alone WM/DE. I've been wanting to learn more about it but most distros offer it only in conjunction with others so that I'm never really sure which is in charge.
At this point i think my additional questions would be better asked in a fluxbox forum. I will, of course, continue to follow along here for Siduction-specific issues. Thanks for getting me started! Siduction rocks!
