I'm looking into how to get this Kill File thingy working on

Oh, my Gosh. :-(
Do you have access to the IDL command line when everything
goes to hell in a handbasket? If so, have you tried typing
Widget_Control, /Reset? But that "checkerboard" thing makes
me think the window manager is corrupted somehow. I'd try
a .Reset_Session, just for grins, before I reached for that
IDL Quit button, but that may be your own recourse.
But I'm becoming intimately familiar with the Control-Alt-Delete
buttons this morning myself, as I can't figure out where this
infinite loop is coming from. :-(
Cheers,
David
