I hear on FB strangeness at time
I recently had all custome fonts that I had installed in FB disappear for no reason.
Also any iApp+safari wouldn't start because I had turned off some system Fonts. I really think FB should warn you that turning of a particluar font will stop an app running or may do.
I know this cannot be covered by all apps but atleast iApps.
Then again now I know what the deals is when Safari will not start.
FB really needs some refinement espacially in how the Fonts are orgaized in the Library/Fonts folders. Any collection you make in FB I think should be reflected in the Fonts folder.
I just noticed I have a library/Fonts2 folder. Whats the deal with that
My 2 cents
