Win7 can run an executable in compatibility mode. I let it figure out which one to use and it chose XP S/P 2. Even so, the computer crashed anyway.

I am investigating driver options and other serial interfaces.

Another possible option is to go back to XP. It was my understanding that new machines with Vista could be licensed to revert to XP, though MS is stopping XP support. Dunno if this applies to Win7 as well. Good luck with it, I will return to my iMac and MacDoppler.......sorry, couldn't resist. I do use XP still...
