I've found only temporary solution by remembering by accepting that evend is
called twice,
simply counting it :), so menu item and toolbar button call the same handler
(both on toggled signal)
in which I've put:

   if(trigger == 0)
   {
    trigger++;
    bool visible = ( (sender == menuItem) ? !toolButton.Active :
!menuItem.Active ); // arhh!
    menuItem.Active = visible;
    button.Active = visible;
   }
   else
   {
    trigger = 0;
   }

hope it helps...
