The datacounter code has several hacks in it, wher:
it shows the ellipse in the multiple images view when there is no common value
it allows for blank entries
it forces events to trigger by setting a bogus value (maxint) before the real value due to limitations in how the updowninteger doesn't trigger events if the new value is identical to the old value.
I don't like the hacked approached... it should be redone properly (although it appears to work).
