It sounds like the installation of fonts in an upgrade scenario isn't as reliable as it should be. What various people are describing here is that some or all of the Mathematica fonts being used are coming from their 5.0 (or possibly earlier) installation rather than the 5.1 installation. We are investigating the problem to try to determine under exactly what circumstances this happens and how to fix it. I'm including some instructions below on how to fix the problem under Windows. If you have difficulties, or are experiencing problems on platforms other than Windows, you should contact Technical Support at support at wolfram.com. First, to determine if you have a problem, copy and paste the following into 5.1... \[ConjugateTranspose] \[Transpose] \[Piecewise] You should see characters which look kind of like a plus, a T, and a left brace. If you don't, try rebooting your system. If the problem still persists, then... * Open the Fonts control panel. * Find all fonts which begin with the name "Mathematica" and delete them (if you find fonts beginning with "Math", you shouldnt' delete those). * Double-check to make sure they're all gone. This is important, since occasionally, multiple copies of a font can be installed, and a font can reappear after you deleted it. If there are some fonts which refuse to go away, reboot the system and try again. * In the Mathematica 5.1 installation directory, which is probably... C:\Program Files\Wolfram Research\Mathematica\5.1 open the subdirectory SystemFiles\Fonts\TrueType * Select all of the files in this directory, and drag them to the Fonts control panel window. You'll briefly get a progress dialog indicating that the fonts are being installed. Sincerely, John Fultz jfultz at wolfram.com User Interface Group Wolfram Research, Inc.
