Yes :-) Don't forget that option values may be bigger than a view bytes. E.g. gamma tables. And SANE also works over the net and constant polling of all options seems rather useless for me. I think it's not that complicated to mark the options whose values can change by hardware (buttons, switches, lamp status, what else?) You could use this auto-poll-every-option mode as a workaround as long as SANE 2 is not ready. But I don't recommend to put it into any "real" fontends, only special button programs. Bye, Henning
