I'm experiencing the following problem with 3D graphics display in Mathematica 6 under Windows XP (with an ATI 256 MB video card): If I display the result of, say, Graphics3D[Sphere[{0,0,0}]] and then use the mouse to rotate the graphic, at various instances the size of the sphere will suddenly grow, and then when I rotate it further it will suddenly shrink. Anybody else notice such behavior? Any explanation? -- Murray Eisenberg murray at math.umass.edu Mathematics & Statistics Dept.
