unfortunately I'm baffled by the lack of anything other than the first frame. The fact that the status bar is getting updated indicates that I'm in my normal rendering loop, and think that I'm rendering frames OK.
Well, there's a pretty good chance that it is something in my local settings. Running on a server edition of Windows is guaranteed to take you through all kinds of interesting option dialogs before you get you 3d apps working with any kind of frame rate. :-)
