Tommy:
Why don't you turn the Vista machine into a gaming machine to keep the kids in the waiting room entertained? That's the only thing that it's good for. You can even get a Wii and put it right next to it so that folks can play "Guitar Hero"! For the serious stuff- stick to XP. The bugs are now worked out; all the drivers work; it's reliable overall.
I agree about the antivirus- Norton and PC Tools Antivirus are really bad. They have a very large footprint and can bring down processing to a crawl. I also like Trend Micro and even like AVG a lot. Occasionally I use a free on-line scanning from McAfee (see

At emrupdate in the past folks have come down hard on MS Access programs for the freeze problems when almost 100% of the time it's a LAN or OS issue.
Very interesting thread, BTW.
Cheers,
Al
