Auto pilot won't follow HDG

[altstiff 71]

I have this problem in both the 737 and 747.The autopilot will not follow the HDG. It will navigate in LNAV just fine but it seems of a few degrees when I select HDG mode. I though at first it was compinsation for a crosswind or something but it's not.Is this the same as the thread below "Anyone with Skewed ND"?Al Stiff

I know this is probably obvious, but make sure you're using HDG SEL and not HDG HOLD.David "jumbojock" Robertson

Posting a screenshot would help.HDG SEL mode does not compensate for crosswinds. If there is a crosswind, there will be a difference between the track and the heading of the aircraft, causing the magenta heading line to not point straight up.
