Yes, that's what I would expect. Selecting different data *should* cause 
another selectionChanged event.

on selectionChanged
       put the dgHilitedIndex of me into tHilitedIndex
       put the dgDataOfIndex [tHilitedIndex] of me into aDGData [1]
       lock messages
       set the dgData of me to aDGData
       unlock messages
end selectionChanged
