Blender freezes

I have some problems with Blender. Sometimes, it freezes. After a few seconds, I have the control again, but the mouse is moved. If I edit something, let’s say I grab something, I need to hit Ctl-Z because this freeze makes me problems. What should I do?

We need more info before we can tell you what to do -

  1. What are your system specs?
  2. What are you specifically doing when it freezes?
  3. Can you show some screen shots or share a sample blend file that illustrates the problem on your system?

Also, it’s always a good idea to include a link to the .blend file you’re having problems with.
