Vue 7.4 (with most recent patch from e-on) in Snow Leopard seems to crash at random times shortly after starting the program or upon exit. I have also seen it crash once after saving a scene, but not able to replicate the results again. Seems to also hang at random times on some scenes, especially the more complex ones with longer render times.

That I used to have with Vue all versions, no change in Vue world ...
Just now, I had a crash with Vue 6.60 (on Tiger) after loading a V4 and try to see if lines display is faster : no it's slower than OpenGL, amazing ! Also with line display, the mouse wheel don't zoom anymore, weird.
Just to say that I don't think Vue will ever work well on Mac.
