I'm not entirely happy with using double click for the user interface either - I may switch to a button or something as you suggest.

I do think this is either  software or a documentation bug though.  I know it's unusual to have mouseUp and mouseDoubleup for the same control but there's nothing in the dictionary that indicates it causes problems.  If the dictionary had mentioned that mouseDoubleup doesn't work in these circumstances, I wouldn't have gone down this path in the first place.  Maybe I should enter a dictionary user comment?

I did see the doubleclickinterval in the dictionary but preferred not to "discombobulate the user" as the dictionary so elegantly puts it!
