Re: Windows version 5.1.1 font bug?
A correction and some good (?) news.... Correction: the font problem with 5.1.1 I had was different from that with 5.1. With 5.1.1, the Front End would force a quit as soon as it started and gave the Startup Error message. Whereas with 5.1, the Front End would start, but the new symbols (e.g., the one for a Piecewise display) would not display. In the case of 5.1, and possibly 5.1.1 as well, the issue would seem to be a problem of getting the new fonts installed when there were existing ones from the previous version. The good (?) news: There's a workaround (similar to the one for 5.1): Delete all the Mathematica ttf fonts from Window\Fonts, then copy back there the ones in Mathematica5.1\SystemFiles\Fonts\TrueType. This is only a "good (?)" news rather than "good" news because the workaround seemed to be necessary, whereas the Windows font issue was supposed to have been solved in 5.1.1.
