Just want to say that 4.0.0.9 worked like a beast during a recent multiple-day art test I took recently. Really put the program through it's paces for long periods of time. It crashed one time and I think that was more a result of some funky drivers from NVIDIA. I am so impressed with all the functionality of 3DC. It's an amazing program. Thanks to Andrew, Raul, Volokh, Sergyi and everyone else I failed to mention who works on 3DC. Love this program!
