I had to reinstall 737NG and since then I cant hold the localizer on ILS appr. I have the ILS freq set in both NAV 1 AND NAV 2.Even if I manually lign up and then switch to LOC hold it still wont stay on the loc course( and yes I do have the proper CRS hdg selected).Rich

Have you tried it with any other aircraft for comparison?Save your location and check to see if say, the default 737 is the same? If so, it's an FS9 fault.Could be, you need to re-install it, maybe?Dave T. .........On the Devon Riviera and active 'FlightSim User's Group' member at http://www.flightsimgrpuk.free-online.co.uk/
