OK, just confirmed that fluxbox and jwm work fine. I had been logging into LXDE, and I still don't see a task bar there. No biggie for me, I like the jwm WM anyways.
A couple of things, while in the LXDE session, I tried to change the Window Manager to Fluxbox or jwm through the Control Center. A message showed up after I choose a WM, and it disappeared very quickly, so I'm not sure what it said. After rebooting, I was still taken to the LXDE session.
Also, when I tried to log in to the openbox WM, all I see is a black window and the mouse pointer.
