I tried to fix it, but it seems that in this part of the code we can't really draw circles; we can only trick the user into thinking its a little circle by drawing a short line. We could draw a polygon with many sides (I guess this is how all circles are drawn on screens?). Is there a program that outputs coordinates in the format required by the code in src/mathed/MathSupport.cpp ? Another interesting issue is that the math decorations do not zoom with the font; (because)? if they did, our approximations would look pretty rough I guess. I'm actually amazed with how well most of them work. I never realized a problem before. Scott
