Kev, Go ahead and install the 4.03. It's a "safe" patch, and it does help clear up many of the early problems v.4 was giving. The freezing you describe sounds like it might be related to OpenGL. Install the 4.03 first and play around with Vue for a day (or several hours), enough to see for sure if the crash problems are still continuing. If they are, the second thing to try would be to disable OpenGL -- but don't do that until after the 4.03 is installed and only if the problems continue. Interesting about the animation timline coming up. I have that happen (since v.3) with every scene I created with v.2. Even now, after I've re-saved some of 'em several times, with new filenames, etc., if the scene was originally started in v.2, it will open with the animation timline - something I never use. I've always assumed it was a minor bug that came in when they added Mover to v.3. I have not a clue why it would be coming up for you -- unless the files were saved from v.2 originally? (I can't recall if you started with v.2 or not.) So...try the 4.03 and give it a good test drive. See how it goes. :)
