Ashadow problem!!

Blitz3D Forums/Blitz3D Userlibs/Ashadow problem!!

Hi friends the last week i bought the ashadow lib and i have a problem when i use PostProcessEffects+Water+Shadow System , it seems that is in the shadow system render.

When i move the camera in specific points of the screen, the objects seems become transparent but when i move te camera again,objects become to normal alpha, and if i see again to the same point, again the objects become transparent.

And this problem appears too if I leave the camera quiet and every X frame of the render make this blink in the objects.

And i dont know why.

I have a Nvidia Geforce 7950 GT, its possible that could be the nvidia card??.

Thansk for your help friends.

Greets.
