Sorry, but all the program crashes, 90 calls to e-on, get one prob fixed and another occurs. I also run most other programs mentioned above with no probs. I am using a new P4 3.GHz with 1 gig of memory and a well know $600 grahics card. Mats won't load correctly, Rock import and resizing causes crashes, and imports and exports are so slow the program simply freezes. Prehaps the next FIX will work. Till then Vue4 Pro sits idlely on my system. Glad it works for some of you.
