TImageEnView.OnSpecialKey is being called twice for each key press (In my case up and down arrow keys or vkUp and vkDown) despite a key only being pressed one time. Can this be fixed please?

Hi Bill

OnSpecialKey is called for every windows event CM_WANTSPECIALKEY message. You may want to suppress multiple events within a short period.

Nigel. I suggest that this event be improved so that end users do not have to add additional code just to to be sure only one key press event is handled by the event. That should be handled internally at the component level, maybe with parameters to detect a single key press.
