D'oh!  I'm getting old.  Or done too many drugs or something.  Forgot
how "real" lists work.  =)

Inlined...

Awesome!  I'll figure out the exact lib(s) that be gumming up the works.

You and me both.  It didn't /seem/ like those would be the correct
settings, but, well, "it worked" where other things that seemed like
they should've, didn't.

It could very well be some side effect that made it work correctly,
vs. the actual settings, I reckon.

Right on.  Just wondering how far under the hood I can peek.  Not
/quite/ feeling like firing up a debugger ATM.  Maybe later, if
needed.  ;)

That's cool.  I saw some demo/example module stuff-- I generally
understand source code better than docs anyways.  Sounds like it's
figure-out-able (not that anything isn't, AFAIC).

Thanks again!
