I've been running 16.01 on XP and have been reasonably happy with it. I feel the stability has improved over 15.7 Cheers!

We are still using 15.7 but a number of our engineers are getting new pc's with the vista os. We never upgraded to 16.0 because of all of the problems I heard about but we know have enough engineers with vista machines that we are going to have to make the jump soon. Just curious. Thanks!
