I'm using lastest 2.0.2 rc12 on windows 7 x64.
There is a problem with auto-repeat for the arrow keys (left, up, down, right) in newt. When one of these keys is pressed and release quickly (so the key auto-repeated should not appear), the events received by newt are:
1) pressed at t0
2) pressed at t1 with modifier autorepeat mask
3) released at t1
Obviously, the event 2 should not be send by newt in this case.
This only happens with arrow keys, and other keys does not receives this extra pressed event.
As far as I can see, this extra event is send by WindowDriver.sendKeyEvent, and by breakpointing, both WindowDriver.repeatKey and keyCode being 0 (ie VK_UNDEFINED).
This bug therefore exists for all other key event with an undefined keyCode (page up, ...).
EDIT: this seem to be related to bugzilla #766
