Well. just to add my two penneth, ive got  v6infinate, and i have noticed the odd random crash, which i have to say i just put down to it being buggy...i remember the same thing happening with vue 5 when it wa released, and the fixed by the service release.
Ive had no probs with any of my plants/objects, it tseems to be happy with all of them, i find it a little odd that it puts its fileing system in to my documents...but hey its easier to navigate too that way, and im assuming that there must be a way to put it on another drive as you can with poser librarys, this will save a huge amout of space .
I have to run these programes off a note book because i work on ships a great deal so my equipment has to be portable, and i have had no probs with vue 5 infinate or poser 6 running on my machine, however i  have noticed that vue 6 inf seems to be incredibly slow!! NO i know that it will be slower running on a note book than on something more chunky, however even given this it seems to be very slow!
I love the idea of being able to use the poser textureing system and pose figures with in the applications as this will make things a great deal less time consuming for me , and it also seems that you can imort a poser scene, and move the bits and peices around with in it individualy with out too much trouble which is again a vast improvement!
I hope that these rediculus copyright issues with plants are resolved and my one biggest wish in the future is that the programme has more basic plants shipping with it, certainly those which some of us payed good moneyt for in vue four, such as the orange tree, the walnut, and yucca, which we find we now have to purchace.....for those of us who upgrade regularly this eems to be a little harsh, and also a rather cheap way of making revenue from loyal customers.
All in all i have always come back to vue rather than any of the other software out there as i think it is an amazing tool which by far produces the best results around!!
So fingers xxxed that thesre bugs are squished in a timley manner and that the proper version is avalible for us all soon!!
