Both are based on the same frameworks Apple delivers with Mac OS X. Maybe it's chance that pollutes the application. The applications seem to take the glyphs they are displaying from a font cache. I don't know how it works, how it can happen that obviously glyphs from different fonts can be mixed up since every font used has a unique identifier and a cache is an organised heap. Skim is also based on these Apple frameworks.<br><br>Adobe products use their own software routines. The PDF displayer of TeXworks uses a Public Domain software.<br></div></blockquote><div><br></div>This pathological behavior is intermittent, and it is possible that I didn't invoke Preview often enough to see it. If MS broke Preview for everybody installing Office 2008 that would be nasty.</div><div><br><blockquote type="cite"><div><br><br>The MS reference you supplied tells that the MS installer would have put the MS fonts into the Disabled folders if it would have found them duplicates of files in the Fonts folders. Why did this fail?<br><br></div></blockquote></div><div><br></div>The MS installer does leave duplicate fonts in /Library/Fonts and /Library/Fonts/Microsoft; for example, Times New Roman appears both places. However, the two instances are different in that the original is a TrueType font with four .ttf files and Microsoft's replacement is a single Suitcase file. That is presumably why Font Book recognizes the duplication and claims to be able to shut one off, but apparently Texshop preview can't recognize the difference nor the fact that one has been turned off by Font Book. Oh the joys of user debugging.<div><br></div><div>-dave</div><div><br></div><div><br><div> <span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0; "><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "><div><div>David Messerschmitt</div><div>Roger Strauch Professor Emeritus</div><div>Electrical Engineering and Computer Sciences</div><div>University of Californa at Berkeley</div><div> and</div><div>Visiting Professor</div><div>Helsinki University of Technology</div><div>Software Business Laboratory</div><div> and</div><div>Visiting Researcher</div><div>SETI Institute</div><br></div><br></div></span><br class="Apple-interchange-newline"> </div><br></div></body></html>
