Ahhh, that makes sense.  I tried it both ways, capitalizing and without
capitalizing, and noticed that it had that behavior.  I don't think I want
to redefine the bang method (scary scary scary).  But, what can I do to fix
this?

*nod + laugh* I've done that in prior little things I've done - Donno why I
didn't do that this time.

Thanks, David.  I'll definitely need to digest all of that and try using it
in different ways.  What I've been trying to do, is if someone gives me a
suggestion, not only do I try and use it in what I'm working on, but I'm
also trying to find another way to use it, that way it sinks in a little
better.

Thanks for the response, I really truly appreciate it.
