Hoperfully I can keep things on a positive note

Paul, have you got the DMK software &/or registax to run on Vista?

???
I see Microsoft are themselves trying to fix program specific problems. I have AVG for my antiVirus and it has a problem on Vista. It will not startup when Vista starts. After I updated, using Windows Update, AVG runs fine, ie always statups.
So let Microsoft know about the Toucam, although they probably already do know by now, hopefully intending to fix it.
I haven't had any issues, except AVG. I've had Vista for 2 weeks now and loaded about 10 programmes (no astro stuff) on it - no probs, inc a 4yo combat jet sim.
