Textures problem

Hello gents,i'm having heavy troubles with my simulator. Some aircrafts don't show all their textures in full screen mode, but in window mode almost everything works fine...In some 2 or 3 aircrafts (the same not showing all the textures), even not having anti-aliasing activated, they produce a similar effect when loaded...making things blur.Does anyone know why is the reasonMy pc's specifications are:P4 2.4256MB DDRGeforce 256 ProUsing DX8.1 Win 2000Nvidia drivers version 32.82PS: I've installed DX9.0 and also the most recent nvidia drivers, but the problem continued!ThxMiguel
