Short description of error
I'm a beginner working on simple exercises. Blender works for about 10 minutes and then crashes.
Exact steps for others to reproduce the error
Create a simple scene with one or two objects and one light. After ten minutes or so things start to go haywire. A second light won't function properly, Other editing functions stop working. I can't change from object to edit mode.
