Thanks for your reply.  I was also wondering; instead of having
the user specify that no window manager is running, is there a
way for the application to automatically detect that?  For example,
twm seems to be able to detect that another window manager is
already running; I haven't been able to figure out how it does
that---do you know how it might do that?
Thanks
