Thanks for the Info!!
It turned out to be the problem alright. I did a search for Runtime +error in "talk graphics" and dicovered this has been a fairly common problem with Xara products, although it seems to be related to anti virus/firewall programs and McAfee's latest Upgrade in particular. At any rate Xtreme Pro is now up and running like nothing was ever wrong.
I thank all who tried to help. It was a very helpless feeling.
