Spot plane view partially missing

Using the 747 PAX (cargo version and all updates installed) parked at CYYZ Terminal 2. I go into spot plane view and using the cursor keys on the numeric keypad I try to "move" the view around the aircraft. I can get no frontal view of the aircraft - all other views are OK. What am I doing wrong?If it means anything I replaced my video card about a month after installing all the 747 updates. I went from an nVidia 6600GT 128MB DDR3 to nVidia 7800GS 256MB DDR3.Mark
