I think it was nVidia and V4 that caused me problems with P7. Once I changed some setting on the video card, my problems went away. Haven't reurned with P8 or PP2010.
I seem to recall that V4 and P7 had a problem with the Morphing Tool also.

What happens when you use SreeD instead of OpenGL? Same problems?

Quote - My Video card is a 896MB NVIDIA® GeForce GTX 260 Core

There are no "over heating" or faulty fans  - lol

As stated before - I've updated the video drivers multiple times.  (except the one time in Jan when Nvidia yanked the driver because it was faulty.

Once the "Freeze" happens - if I relaunch right away, and even just load the default low res "ball" prop - it will Re-Freeze when I try to delete it.
