Simmerz,i just re-installed my PMDG 737NG products, after i got a new PC, and i noticed that if i am, i.e. sitting on a runway (any runway in the world), on the ND, it shows the runway to my right or left. ASWELL as my route and Navaids, waypoints etc.So it seems that the position of Runway.XX in FS is different to the position of it in the NavData base. I am using Ground Enviroment Pro, with an Aussie Landclass addon. But i cant imagine that affecting the position of everything.ThanksDan

The FMC "maps" only the runways selected for DEP/APP, if you are sitting on the same runway as the selected departure runway and the runway is depicted someplace else, then it is likely that you have a problem with your airac data. You didn't mention if you're using a recently database from navdata, might give that a try.
