My touch is more "touchy" about losing the library. This is using squeezecenter on an Imac and the library on a networked Mac mini. Neither one of the duets currently in service had this problem nor the Boom. The SB3s are currently not in use, but they never really had that problem either. My quess is that it is an interaction with the built-in server software as well as perhaps polling of the USB port. But then again, I'm certainly no expert.
