And why do you think the fridge manufacturers will get it right in cheaply-made consumer-grade products, when it's not being done right in muh pricier automated self-check-out checkstands? I avoid self-check-out checkstands because they fail in one way or another so damnably often. My last encounter had the software failing to realize that a package of 100 nuts and 100 screws weighed a significan amount; the result was that for each such package I tried to check out, I had to have someone from the store come over, log in, do something, and log out again. Five times total. *Not* satisfactory. I don't expect that the fridge makers will do any better. -- Mike Andrews, W5EGO mi...@mikea.ath.cx Tired old sysadmin
