Hey everyone!Please excuse if this has been discussed earlier. But today I experienced a "new" Problem for my PMDG 73NG.I simply can NOT track a Heading using the HDG Selector. When its tuned ON the Plane keeps the current Heading. When i try to manipulate to some other course it does nothing. it just keeps flying the current course.And since this happened i cannot capture any ILS approach.It just keeps flying an interception heading, cross the "approach centerline" and goes off to somewhere else.The Glideslope works normal.Can please someone healp me out?RegardsThomas

Thomas,What does the roll mode annunciation on the PFD say when you're seeing this happen?
