Whoops! Of course, you have to put the state structure back. The code
should really look like this:

thisEvent = { ID:parent, TOP:ev.top, HANDLER:0L, VALUE:value, DRAG:drag }
IF state.event_pro NE "" THEN BEGIN
Call_Procedure, state.event_pro, thisEvent
thisEvent = 0
ENDIF
WIDGET_CONTROL, stash, SET_UVALUE=state, /NO_COPY
RETURN, thisEvent

Cheers,

David
