No, I don't remember anybody reporting anything like this. I would suspect a file system bug if the permissions reverted after a short time, such that a change was made in-memory, but was not written to disk. But if it happens roughly every month, it's more likely some outside force is changing the permissions. > Sonny -- David Kleikamp IBM Linux Technology Center
