Chuck, one of my scenes (over 100 MB big) has been tested by e-on. It's clear, it would not crash on a 2 Giga Ram:-). I had more then 4 very high resolution bitmaps in it (4000x4000). When I disable all what Steve said, it works without crashing. Before I had about the same problem as you, could not add and move and so more then 1 object, had to save the scene, shot down Pro (often even reboot my computer), because otherwise my Pro would crash. Pro needs VERY much more memory then Vue 4 with all these undos... BTW. I did not say that "a 2.8 machine is an old machine". Mine is "only" about 6 month old. (Of course, for a computer seller that's already old. LOL)
