Yes. Like this:
;Get the structure name of the event
Case Tag_Names(ev, /Structure_Name) Of
;Tell the user what to do. Event is generated when an object is
mapped/started.
'INFO': Begin
Widget_Control, self.info, Set_Value = ev.info
Return
End
...
This is indeed executed and then processing stops until I move the
mouse. There are no further events involved...

I am afraid so.
I just had the hope this was some known phenomenon.
Thanks for your help anyway!
