Parts of the contained_by box shows up in this scene.

My system: Duron 700@900 Duron, 512 SDRAM.
Pov version 3.5 beta 1 on Windows 2000. 
The iso appears as expected in MegaPov 0.7

#declare S=.4;  // setting this to less than .5 gives strange results
#declare L=.5;  // setting this to 0 still produces artifacts
isosurface {
    function { L*sqrt(cos(x/S)) + y^2+z^2 }
    threshold 1
    max_gradient 10.77
    accuracy 0.01
    contained_by{box{-<.8,1,1>,<.8,1,1>}} 
    pigment { rgb 1 }
}
light_source { 5,1} 
background{rgb 1}
camera {location  2 look_at 0}
