It is always a difficult question. How to define "stability". I work with all versions of Vue from 4 over Pro to 5 and Poser on Mac and don't have more problems than with other programs - or the operating system itself. I know there are some issues when other applications (i play some games, chat or surf the Internet often while working in Vue) run the same time as Vue and/or some issues with the Wacom tablet driver. But these problems other applications like Cinema, Quark XPress, Freehand do have too. Right now i prefer to do my scenes in Vue 5, feels good to me (in capitals: TO ME). I only miss some Pro features and therefore go back for parts of scenes to Pro as well. To me 5 is as stable as 4 is but feels smoother in the workflow. The results with the expanded light options are outstanding. I even re-render a lot of my old scenes right now and exchange the gallery entries here slightly. I don't give you any advice - applications can react too differently on specific systems (for example i threw away the new Internet browser Firefox because it was not working properly on my system - even when the whole world is jubileeing about it). Conclusion? None really. Maybe you try out the trial version and see - the closest you can come to the real thing.
