Strange AI-traffic behavior in fs2004

Hi all,I was doing a long haul flight behind an AI aircraft on the same route-The Ai a/c kept veering off course and had to keep correcting itself. I did a couple of other flights and the same problem persisted. I traced the problem down to the real world weather setting(with winds aloft). For some reason the Ai aircraft are not able to deal with winds at cruising altitudes. Is there a fix for this?. Part of the fun on long haul flights is watching AI a/c and seeing them weaving around is somewhat irritating.RegardsBharath Narayan
