[osg-users] glPointSize no longer working for me?

I tried adjusting the point size using osg::Point but it still had no effect. By the way these points are actually osg::PointSprites if that makes any difference.
I queried OpenGL using glGetFloatv to find out the range of supported point sizes on the machine and it returned 0.0 to 64. I also tried enabling and disabling blending as well as point smoothing, no difference. This is puzzling because this same code used to let me change point sizes. :(
Please let me know if you have any other ideas.
