Masking is not working properly with quiver, while it works fine > with contour -- see the attached quivtest.png This is a numpy.ma bug that has been fixed in numpy. I don't know exactly when it was fixed, but after I tracked it down to numpy.ma, I updated my copy of numpy from svn, and the problem went away. Somehow, when a multiplication was done with broadcasting, the mask was getting handled and propagated incorrectly. I suspect this bug was present only for a moderate interval of time, because quiver with masked points worked for a long time before you ran into the bug.
