Well, it turned out that Norton was the culprit. I uninstalled Norton, and the .exe files worked just fine. I have used Norton for years without problems (except it's slow), but have heard warnings that it can interfere with other programs. It just hasn't bit me until now. I guess it's time to look at other security utility packages. Igor, I doubt this is worth pursuing on your part, but if you want me to send you any information, I'll be glad to. Guess I'll take my wife out to dinner. You're welcome to join us!
