Thanks, Derek! It took me some looking and experimenting, but this is a great idea. I see now that os.nice() works for Mac too, and Gabriel has some suggestions for Windows. So simple- I was thinking I needed superuser access to set priority to real-time, but I don't need it to raise the priority of a running process. I never would have thought of that on my own. -Chuckk -- http://www.badmuthahubbard.com -- http://mail.python.org/mailman/listinfo/python-list
