I chose saute to heat up a frozen sauce. Then it stays forever at saute and I cannot even change it. I chatted with the company, the reply is, just wait for 10 minutes for the computer to reset. I unplugged the unit, and waited for ten minutes, no effect. The designer is as stupid as I can imagine -- probably with the intelligence of a pig -- no pigs are more intelligent than these designers. Do not buy this product. Advising people to wait (essentially overnight) for a reset is not acceptable. Unfortunately I bought it two years ago and there is no way to do anything about it. I hope the stupid management will read this review.
