Just spent about 5 hours with my new terrain open offline DX9 executable. I was upping from all feilds to review the land around each field from an airplane. I minimized the game during that a few times to check things in Windows but always in the tower. The only path objects in place are 28 view only rivers. When I exited, the game froze and I had to Ctrl_Alt_Del to get the task manager. At that point a windows error popup was generated for the AH DX9 executable. Attached is the DMP file.
