Gerry asks: Next post SP1 prob, unless it's coincidence, is with slew. Num pad's 5 key always fixed the current slew position. So if I'd pressed Q to increase altitude, pressing 5 would stop its ascent. Now it has no effect. I've been looking through FSX.cfg, to see if there'a a key allocation but can't find one. Use the 'A' key to slow/stop/reverse the ascent. Paul
