I have Blender 2.5.2 for Windows 64 bit and it keeps giving the “Blender exe. has quit unexpectedly”. It seems to happen a lot when I undo a piece of sculpting, and sometimes when I do an individual render.
It is quite annoying.
Any suggestions as to how to fix this?
When rendering I believe setting the render display to a new window is more stable than rendering to the default full screen.
As for blender crashing, I guess its just the way with software under development, its going to be more unstable than fully tested versions. Maybe downloading a more recent build may have overcome any bugs you are encountering.
