I saw that, and found it a bit confusing.  Neither of the calls to
this function relating to this bug were doing their job, but other
calls to it did seem to work.

Ah.  Thanks.  That's important to know!

I'm actually just doing old fashioned trial and error debugging (no
firebug involved).  Even after waiting a considerable time, the calls
to ASTGUI.systemCmdWithOutput() didn't do anything.  Perhaps they were
defered in favor of something else that was failing?

Hmm.  I put some alert()'s at the beginning of the call-back
functions, and they were never run, so apparently the call-back
functions were never called.  I dunno.  I'll dig more.
