Hi Rick, your package was extremely helpful for someone like me who never used multi-threading out of fear of the possible complexities. I tried your examples and it worked like a charm. Only, I had trouble at first reading the doc. So, I compiled a help file using basically what you provided in the procedure file, just to give your well-written words a bit more "air". If you find it helpful, you could include it in your package. I claim no authorship whatsoever, of course, just did it out of enthusiasm. Thanks for your effort!
