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
