I think more clarification is needed as to what Otto's doing under a given set of prefs. Beyond the danger of having "fix broken links" activated under Otto (unless your library is completely static, as mine is not), it seems that Otto is getting it into his head that certain files are missing, even though I can play them in MC. I can view them in the MC tree (although they have yellow icons), play them in MC, yet I cannot view them in the audio library, and I blame Otto for this.
