I don't know if this problem is in FontBook or what. I keep turning off my fonts and they keep turning themselves back on. I cannot find any rhyme or reason. I started by turning all fonts off. Then I'd open up photoshop and a whole bunch of 'p' fonts would be on. I eventually traced it to an AdobeFnt07.lst file. In fact there were about six of these scattered in various place. I deleted them all and Photoshop remade them without the extra fonts. I thought that was solved then after working for a while I see that another bunch of fonts have been turned on. This time all the p fonts again. And I only had Illustrator open. So again I turn them all off. Start up Illy and everything is fine. Start up Photoshop and everything is fine. Then I have a look in text edit at the fonts and I find that all the p fonts are listed, but they don't work. I check with FontBook and they are still off. I'm wondering what it is about the p fonts. Any way all the fonts in FontBook were still off. Then after opening Illy again I find that a whole bunch of fonts are back on. This time the T U and V fonts, (not every one but most), sure enough I check in FontBook and they are back on again. This is really driving me crazy. What is causing this mad behaviour.
