Have no problems like that with both versions, Mac and Windows (2000). I installed the Windows version yesterday, updated it with the last update downloaded yesterday and since then it happily is rendering a scene i setup on my Mac. My feeling is that Pro has a conflict with something else on your system. Maybe you go through the components and think about this options. Example. I have problems sometimes when the Yahoo Messenger is running the same time as Vue is, i always have problems (on Mac) when i want to use the Wacom tablet. And that not only with Vue, with Cinema and Poser too. So there are many many things that can cause that. Be sure that many many more would have reported this issue when they would have it. So it must be something which has to do with your specific settings.
