I think these key ups are in fact generated by the keyboard. So autorepetition
has to be switched off at rather low level (kbdrate - unfortunately it does not
seem to disable repetition comletely.).
What we did here in BFAD was to have a filter receiving characters.
If after Key_up key_down was received "immediately" (say within 50ms) such pair
of events was ignored.
Best regards,
