Dave, I had Vue 4 first on Windows 98 first edition, PII-300. Later I had it on Win ME, PIV-800. I went back to Win 98 (always first edition), because I did not like ME. Vue 4 worked absolutely fine and without any problem since I had updated to 4.12. Randomly it crashed, but this happend maybe 4 or 5 times a year and believe me, I used it EVERY day for hours, because I'm working with it for my professional work. Windows itself crashed lots more often. Now, I have installed Vue4 on XP Pro- P IV - 2.8 and it also works great. As Vue Pro doesn't run on Win 98, I also have Vue Pro on my XP computer. On this computer, as I said already, I only have graphic programs, nothing else. No shareware, no freeware, no games, no illegal copies of anything!. I have installed Vue4.12 3 times on this computer, in English, German and French language to be able to help out in all these languages with the right words, as I'm also a mod at French and German groups. My Vue Pro has not crashed once since I have installed it. I have done the most crazy things with it, mixing 4 and more materials and always trying and doing more then what is logically possible. Every program has its limits, I often overrun it with Vue 4.12 and Pro and it works :-). Vue Pro has been tested on lots of computers and computer powers and graphic cards. But it cannot be logically be tested on every computer Brand existing in the world. I would bet that Vue (any version) works ALWAYS great on any "clean" computer with a clean OS installation (speaking about PC, I don't have a MAC in my small collection). I either can't see the "enormous amount of bugs" you are speaking about. What are they exactly? If ever we find bugs, we report it to e-on and they will do every thing possible to give us satisfaction. If you found bugs, you should report them also. I'm curious to know what kind of bugs you are speaking about. When I have an enormous scene ( over 120 MB) to render, I also shot down every thing else by msconfig, that's just to make render faster and sure. Finally, please don't compare Wings with Vue:-). :-)Guitta
