I haven't tested this, but if you set the RETURN_ID keyword,
you will get the ID of the selected button back in the VALUE
field of the event handler. You could store this value as
the current selection:
info.current_selection = event.value
Then, when you wanted everything to be insensitive, you
could do something like this:
Widget_Control, info.current_selection, Set_Button=0
Cheers,
David
