Hello,During a short flight between SBGR and SBGL, two big Brazilian airports in Sao Paulo and Rio de Janeiro, I noticed that PMDG 737NG did not follow a hold track introduced in the FMC and, worse, lost the approach track completely.The flight plan was followed perfectly until the beginning of the SBGL approach, where it has a hold on waypoint CAX.However, few miles before the hold entry point, the 737NG made a sudden curve to the right, the contrary side of the hold, and followed a straight-line, moving away from the approach track. The FMC did not command any more the airplane. I repeated many times this flight, and the problem occurred in all of them. I took off all the factors that could contribute for the glitch, as wind, large weight, speed, without success. In all of them the airplane didn

Nobody observed this problem so far with 737NG?Could somebody please make this flight just to verify? It's a very short flight, so it does not go to take much time.ThanksValter
