I too have had my share of crashes with Vue under OSX 10.3, with both a G4 and now more so with My Newer G5. (1.8DP, 1GB RAM) I tend to believe that it is the app itself and not a system related problem, that causes so many crashes. I don't have these kinds of issues with any other App I use. But if you look at Vue4 on Mac from initial release to today, they have gone a long way on stability from the first Mac version, which on my systems was almost unusable. This tells me that we can expect that Vue5 will but much more stable on Mac... :-) Paul
