Oops.  :-[

Well, I must have grabbed that code from someone.  I'm going to go find 
someone else to blame for my problems...  (just kidding)  But seriously, I 
think I did find those settings somewhere else from someone who used photons 
to do something pretty nifty.  I guess I'll have to experiment more on my 
own.

But thanks for letting me know!  :-)
