This problem has just shown up on a number of machines with our introduction of a new higher resolution world map file that contains a large number of polygons. If you cannot update your driver or if the update does not fix it you could turn off the display of that particular map. -Jeff Ticket Details =================== Ticket ID: FAK-572697 Department: Support IDV Priority: Normal Status: Closed
