Worked: 2.71 No issues
After working in Blender if high Density mesh (1 Million +) when I leave to browse email or other apps, on return Blender will crash. Doesn't seem tied to any action or function, just a wait period. Can't seem to duplicate it using tools. I did have Blend4Web installed but unchecked it as it wasn't supported. I do have Pie Menus running. I will try without and see if that makes a difference (If no further updates then crashes still occur).
Exact steps for others to reproduce the error
It appears to happen after I leave Blender for 5 minutes and return. First action on return will crash Blender.
I do have a crash report I can attach.
