GBs vanishing AU Modules

[Sasha3]

Have a number of AU plugins installed properly that will sometimes appear in the AU modules list, then vanish suddenly, then reappear with no apparent pattern so as to clue me in to what is happening here. OS glitch or what I don't know. Any ideas?

Are they ones that you have added or the standard apple plugins? Does it affect the apple plugins at all?

They are things like Crystal and Buzzer2. Third party synths. Standard Apple plugins? I don't know to what you are refering.
