[DogParkList] contest helper locks up

[EZ Rhino]

I've noticed some quirks with the contest helper window.   
Occasionally it will lock up.  I can't click on any part of it to  
move it out of the way or alter it.  I have to close MLDX completely  
and reopen to continue.  Also, occasionally the contest helper window  
will close itself and vanish.  Has anyone noticed these quirks?
