General abort command

Is there a general abort command in Rhino? When everything has stopped, just a little wheel turning around…

if esc doesn’t do it, then rhino (or windows) has crashed.

better question is what are you doing when the wheels starts spinning and what is your systeminfo (type that into the rhino command line and paste the report here)

that will help us see if your machine or set up is having issues that we can help remedy.
