Narrative:

I was PIC. On the climb out to the cruising altitude with the first officer flying we discovered a computer malfunction that was a requirement for our present route to cross on the nat tracks. After involvement with dispatch and maintenance it was determined that landing back at departure airport and getting it fixed was best course of action. The flight was heavy and we landed overweight. The landing weight was about 329;800 pounds; landing and rollout were normal; ground maintenance did the required inspection; computer problem was fixed and we were able to fly to our schedule destination.
