Hi Chris,

ah, good. I think it was like this:

1. You got three events: key down, key stroke, key up
2. Key down went into the event filter in the scroll pane and falsely used
to scroll: 3 lines.
3. Keystroke was converted into mouse wheel and handled as mouse wheel: 3
lines.
4. Key up went into the event filter in the scroll pane and falsely used to
scroll: 3 lines.

The fix corrected 2. and 4. 

Best,
Marcel
