Tom, i agree with you that a discussion is good and helps all of us to make Vue better. It would be a big help if you can give a little more information about the scene(s) you have trouble with. Otherwise for me it is like operating with long sticks in heavy fog. Maybe you make a screenshot and/or a rough render so we can see something. From time to time, when i definetly want to finish a scene and Mac Vue is not able to, i switch to a windows machine in the office. Maybe that is a possibility for you too (of course not our machine in our office :-)) ). Before spending money for new software perhaps it makes sense to spend money into a windows machine as an add-on. That offers you as well some "windows" to software that is not available on a Mac too. I found that there is no danger to switch completely to Microsoft, but sometimes it helps.
