I think this will work. It's a little bit quicker than the method Alec
mentioned (and which I use in another part of my app) and it's definitely
a little less confusing. I just tested it by opening a couple other
instances of Notepad before running it and your script kills only the
Notepad process that it opens, as expected. Very cool.
Thanks for helping me once again.
Mike
