A couple of questions, if anyone can help: 1) I have added arrows to the QuickFix list, using \ra for a right arrow, &c. \ra will turn into U+2192 in Times New Roman, but I can’t persuade anything to turn into a ‘heavy rightwards arrow’ U+2799 in Zapf Dingbats. Anybody know how to do this? 2) I finally got a free-software package to work as advertized: Sage, a 1.66 GB (3-hour) download. It is a Mathematica/Maple/Magma/Matlab replacement, happily computes pi to 5000 places (so far), its light-shaded 3D objects rotate as fast as the mouse moves (and much faster than I can draw similar polygonal skeletons in my rainbow calculations), so it has been highly optimized. I mention this because, working with 200-page files, I find Nisus painfully slow on saves (as is Spotlight’s or Google Desktop’s subsequent indexing). 3D rotation involves mouse-tracking, rotation-translation-scaling matrix specification, matrix multiplication of the object’s homogeneous matrix (an [x y z 1] row for every point}, and converting the 3D results to pixel coordinates in the graphics memory. The last step probably has dedicated hardware these days, but rotation still seems more complex than saving an RTF file! I guess the question is whether Nisus is slow because formatting and unformatting RTF are intrinsically CPU intensive, or slow because Nisus wraps the job and passes it to Foo who wraps it and passes it to Bar ... until it works its way down to active code. -- Ferren ------------------------------------------------------------ (Dr) Ferren MacIntyre 1 Chemin des Echarts Campagne sur Aude 11260 France ------------------------------------------------------------- OSX 10.5.8 MacBook Pro 5,1 2.4 GHz Intel Core 2 Duo, 2 GB
