I had been running LyX 1.6.3 with MacTeX 2008 under OS X 10.5.x and created a number of documents using the three Bera fonts.
Recently, I downloaded, installed and updated MacTeX 2009. I also grabbed the MacTeXtras; it came with LyX 1.6.5 so I installed that also. Now LyX doesn't see that the Bera fonts are available (they show as 'not installed' in Documents -> Settings -> Fonts). If I switch back to MacTeX 2008 (which I have not uninstalled but would like too) and reconfigure LyX, these fonts still show as not installed. MacTeX 2008 and 2009 most definitely do come with the Bera fonts installed; all the correct files appear to be there. I really need to convince LyX 1.6.5 that these fonts are indeed installed and available, as I need to re-edit some documents and have them print using the same standards that I was already using for this series of documents. (And yes, I did re-run 'sudo texhash', just in case, and ran the LyX-installer that comes on the LyX-1.6.5-Mac-Universal.dmg.) Any suggestions would be appreciated. I haven't yet downgraded to LyX 1.6.3; I guess that might be my next step in troubleshooting. Thanks, -- Rich
