Narrative:

While on the maier 2 arrival to runway 8; the airport switched to runway 26. I reentered the maier 1 arrival (to get the points for westerly arrs) and entered runway 26. The aircraft went into heading hold and I failed to reestablish navigation trk. After drifting about 1 mile south of course; approach control told us to fly heading 180 degrees and handed us off to another controller. There was never any traffic conflict.
