<b>Wolfram/Apple patch to Apple's Appearance Extension designed to fix a bug in Mac OS 8

Appearance Extension bug According to a page on the Wolfram Research web site, there is "a bug in Mac OS 8.0 and 8.1 that affects Mathematica 3.0. This bug manifests itself in several different font-related display problems." These include:

Spaces between words in text disappear
Cursor appears several characters behind the actual text insertion point
Copied text not being pasted correctly
Special characters of MathFont not displaying correctly

"In most cases, simply quitting Mathematica and rebooting will get rid of this bug in your current session. This Mac OS 8 bug resides in the Appearance Extension file." Even better, Wolfram and Apple, working together, have created an Appearance patch that permanently solves the problem.

Does this problem relate to other reports of problems with Appearance Extension (such as those noted with Eudora Pro)? Will this patch also fix these other problems? Let me know.

Update: The patch does not work on Appearance Extension version 1.0.2 (the version included with Eudora Pro). The patch claims that the extension is the "wrong" version. (Thanks, Francois Schiettecatte.)

Mathematica bug Wolfram have also confirmed a bug in Mathematica 3.0's Mac front end that causes on-screen line breaks to occur about 1/4 inch before the right margin. The problem does not appear when printing; thus on-screen page break indicators are useless, and page breaks must be tweaked by trial and error. (Thanks, Selwyn Hollis.)
