Ok. The e-on thread does not really say much. Sometimes i have problems when i click too fast. Then Vue does go in an endless loop and i have to shut it down. That is not your problem. Fatal errors i only get when i am using imported objects with a lot of facets. Trees or splashes for example which have more than 500,000 facets. Then i "receive" indeed a lot of crashes or fatal errors. You can check it with your file sizes. My maximum scene was around 600 MB big, but had only around 10 Mio polygons. As i said, imported 3DS-trees let Vue memory quickly "explode". Before Vue 4.12 the limit even was around 200 MB so we are a big step further. Let us know. I am nearly sure that something like this is the problem.
