Installing the FS9 update fixed the exact same problem I was having on my
Toshiba Satellite 5200 with Nvidia Geforce FX Go5600 display adapter.
Toshiba have never released a video driver update for this adapter since the
5200 was released to market. Now FS2004 is running full tilt boogie !!!
Good luck. Hope this fixes your problem as well. Regards Jim
