Oh, and I am working on IDL Version 8.2.2, Mac OS X (darwin x86_64 m64)

It usually works well, but when moving the cursor too fast (or for too long?) the widget will freeze. I can't close the widget, and hitting the .reset button does nothing. The Workbench behaves as if this is a modal widget -- which is not -- and does respond to any commands. The only way I can proceed is to exit IDL and start all over.

I meant to say that during a widget freeze, the keyboard does *not* respond to any commands.
