"EXIT" means "Exit from IDL," not "Exit from this routine."

If you wish to quit from a procedure or function, use RETURN, or just END
the routine as you would normally.

You can not issue an EXIT (from IDL) command from within a Widget routine.
You can from other routines, but XMANAGER prevents you from aborting a
Widget-routine with a STOP or with an EXIT.

Hope this helps,
Joel
