Just verified my 64S, NSB 32, S1, UC (S1 & UC on imac 15) are updated, SB direct connect to board, board networked to mac, board also USB to mac. I power on SB, then 64S, then when finished booting, start S1. Board frequently not showing in s1. When it does show up, if I select the board in S1, then the SB inputs will disconnect. I cannot find any S1 setting that turns off AUTO SETUP (I read that somewhere). Seems like a sync issue. Board and SB will function fine together, have board set to internal clock. What am I missing?
