nope - I cannot now reproduce this problem :/ next time I will make copy of 
"bug producing" scenes

1. but i'm shure that ther IS something wrong with dispersion.
Suddenly pov started co render pure black sphere instead of glass, after 
just closing Pov, and instantly opening it back again - everything was o.k.
Scene - one plane collent on, one sphere :
rgbf .9, dispersion (about 1.1-1.3), ior (about 1.3) 
all was rendered on mosaic-preview

pow(x-U,2)+pow(y-V,2))*.3)),2)+.9)#end#macro p(c)#if(c>1)#local l=mod(c,100
