Thanks Marty; this does indeed help...it just also means I need to really
learn how subprocess works. ;) I wish I could claim to be using 2.6, but
unfortunately the most current version at work is Python 2.5.2...most boxes
here are even below, and I can't convince them to upgrade. Ah, well.

Thanks again though!
