Interesting.  So when it restarted it probably thought it had some command 
line arguments and those were junk so it gave an error message.  Well, 
that seems the most likely situation to me but it's odd it didn't give any 
other messages since it should have.  The code that actually starts the 
GUI proper is only run after all that usage() stuff is out of the way, so 
even if the former throws some kind of exception (without crashing) it 
wouldn't (or at least shouldn't) trigger that usage message.

On the crash front, it would definitely crash if glutInit is not run (and 
if glutInit needs to be run).  So glut (and OpenGL in general) are 
extremely intolerant of errors.  Now in the current code glutInit is only 
called once (period), not once for (say) every new window, or every new 
strip.  And that's how I understood it should be done.  So it should have 
been called when the first HSQC window opened up.  So I wonder if some of 
the glut internal variables somehow got trampled so that it thought it had 
not been initialised, hence the error message (which would be bogus).  Or 
maybe there is some threading issue here, although we don't (knowingly) 
muck around with threading so that shouldn't be the problem.  So all in 
all a mystery.  Out of curiousity, which OS variant/version are you using?
