When I zoom in to close to the red line, the program becomes very slow, and when going closer, Windows says that it must close the program. This is only a small problem, but was a nuisance when I had to check if the Lua script was doing its job! I don't know if anyone else has had this problem. Ivan Slabbert I have a "special" way of drawing the contours so that if part of the contour is erased, the entire screen doesn't have to be redrawn. I was sort of sloppy about how I implemented this--when you zoom in, the routine spends a lot of time dealing with parts of the contour that aren't in the viewable area. I'll fix this so that it is better-behaved (i.e. neglects drawing parts of the contour that aren't viewable). Dave. -- David Meeker email: dmeeker@ieee.org www: http://femm.berlios.de/dmeeker
