Stop Animation Generation

I was trying out the animation feature and was wondering if there was some way to get Rhino to stop generating an animation?

I ended up having to kill Rhino to do it.
I’ll also add that when you set up an animation, the default output path is for WINDOZE.

When I try to record an animation, my system locks up with the spinning beachball and becomes totally unresponsive. I see a few frames (shaded view) then everything stops. I can run the animation with no problem.

Add: I did get one to record after several tries. There is some problem of interaction with the OS. When Rhino creates frames, Finder cannot see them. I had to restart finder to see them in the directory.
