Gunnerjohn and GGG - Many thanks for the excellent suggestions, and I'm happy to report that the factory reset (something I always seem to forget) took care of the problem and the Aerotrain is running beautifully in conventional mode. Question for GGG: curious, what exactly is a "supercap?" Not a term I'm familiar with.
Again, thanks guys! This Forum has been a lifesaver!
