One more [last] comment. I've found that although I can't hold the slider and move it using the glow and grow feature, I can "paw" at it and get it to move in small increments at a time and eventually get about where I wanted it to go. Also, the whole problem seems to resolve itself once in awhile before going bad again. I can't figure out what the trigger might be. I'm losing some confidence in these mixers. If I had any real serious work to do, I might be checking out the competition.
