I have updated my Vue4 Pro with the Beta and it didn't improve matters - the program is still very unstable and unpredictable. I have 1GB of ram and it still runs out of memory so I'm upgrading to 2GB in the hope that this solves some of the problems. I suspect that there is a memory leak in there - somewhere. It's a shame that two of my favourite programs are very unstable Poser 5 and V4P but I live in hope that they will eventually be fixed. Vue 4 is far more stable than Pro but I've been spoiled by the features and won't go back now. At least registered users of Vue can get fast support which is more than can be said for other programs - not mentioning any names :)
