The following is a list of known problems with the Curve Educator. If you find a problem with it, please send me a note. Thanks, Dav de St. Germain.
1) There is a small gap between segments of the curves. I'm not sure if I call this one a bug or a feature, as I left it around to give the user feedback about where one curve segment ended and next began. However, after adding color to the segments, this is no longer as important. It is also potentially confusing because sometimes it looks like the curve doesn't make it all the way to a control point. The quick fix for this is to update "time" (the black dot) and see if it actually goes over that area of the curve. (This problem doesn't occur very often so I haven't looked into it more.)
2) Basis functions are not always drawn "smoothly".
3) Some status bar information hangs around for too long.
