When I try to specify 5 degree increments for the rotation steps, the amount of rotation actually is much bigger and unpredictable. Does Manipulate have a problem handling degrees as increment amounts? http://home.comcast.net/~cy56/ManipulateBugDegrees.png http://home.comcast.net/~cy56/ManipulateBugDegrees.nb Manipulate[ Plot3D[ Sin[x y], {x, 0, 3}, {y, 0, 3}, PlotRange -> All, PlotStyle -> Opacity[opac], PlotPoints -> plotPts, MeshFunctions -> ( {x, y, z} \[Function] z), Mesh -> mesh, MeshStyle -> Directive[Gray, Thin], AxesLabel -> {"x", "y", "z"} ] /.
