In a GEMS 1.5.10 election, ballot 
    style, ballot, card style and card are expanded in the tree view.  
    Resetting ballot artwork (Artwork, Reset Artwork), then double-clicking on a 
    ballot style, ballot, card style or card results in an internal error.  
    How about Reset Artwork making the ballot threads automatically collapse so 
    as to prevent this?
