Pro - Yes, often you can do stuff in Poser with a script minimized. I have found it a bit twitchy though. That's why I've been recommending closing a running script before doing other Poser functions. You can already delete MTs in Poser. Just open the heirarchy window, select the view for all options, select the MT you want to delete and press 'DEL'. No point in re-inventing the wheel. ;-)
