Hi, using Win 7 64 bit with 2010 SP2, we are getting the B(Black)S.O.D. after about an hour's worth of work, this happens on 2 machines, all drivers are up to date and correct. When it happens we are still able to see the feature manager, but not the modeling area, any body else having similar issues? The video card is FX 3500. Also, sometimes the file becomes corrupt and endsup empty, we are not using photoworks so the hotfix does not apply to us.
