David, I don't think you need assembly! Using Jacques port.e : include ports.e procedure wait_for_vtrace() while and_bits(Input(#3DA),8) do end while while not and_bits(Input(#3DA),8) do end while end procedure It should work, but it will slow down things somewhat. Fortunately, I do not have a problem with flicker/jitter on any of my machines, so I can't really test it; it must be hardware dependant. Let me know if it works. Jiri
