I do not believe that the installs of AutoIt, SciTe, or AutoIt Beta, has anything to do with my problem. These AutoIt programs were developed on another system, and I have verified that they do work on other systems. I guess, the sort of help, I am looking for, is internally, what does the Run() program do? For instance BAT programs exeute external programs OK, but all of a sudden, my AutoIt programs fail. Looking for help to detrmine what is fouled up!!!
