Thanks for testing this out.

Lol. Yeah, I wasn't trying for elegance. I was making sure the code and
results were absolutely clear.

I have friend with a real Windows machine that will test the code of the
app where I applied this technique so, hopefully I'll be able to see if it
works on a real PC and if the problem is Parallels. I'm a Mac guy too and
only use Windows to test apps built for both platforms.

Thanks. I'll let you know what my friend turns up.

I did work a little bit in the script editor under Windows and didn't
notice the awful problems you've been reporting, but again, it was just
some tweaks and code changes. I don't do most of my scripting under
Windows. I hope this gets fixed.
