"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

I do not know the reason for this, but I can tell you, it's not
the wdelete or widget_control command you used -- at least, only
in combination with some other command. I use exactly the same
widget_control command and I added the wdelete to my application,
but every thing is o.k. (I use IDL 3.1.0 on IBM RS6k)
Good luck, Ralf
