I would like to suggest this is not a bug. When you click between two cells very quickly you are double clicking on the grid. The event being dispatched represents this correctly and I have had cases where I would want it to dispatch this event. 'Fixing this bug' would break functionality of at least one project I have worked on in the past.

I've had the same thought and have had to do a lot of confirmation of the double click event (was something selected, was that thing clicked on both times, etc) and I agree something needs to change, but this is definitely a feature and will change existing expected behaviors. From the AS3 grid documents: http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/spark/components/Grid.html

"doubleClickEnabled : Boolean
[override] Specifies whether the UIComponent object receives doubleClick events."

I suggest closing this issue and requesting a feature where the grid dispatches a CELL_DOUBLE_CLICK which can be enabled with a new property on s:Grid or perhaps that there is a new property which indicates doubleClickMode = "WHOLE_GRID||SINGLE_CELL||ROW||COLUMN"
