Thanks Darryl I didn't notice the problem until I upgraded to 2.0, but that's not to say that it wasn't before, because it started off being very rare (just one incident of an encoder spontaneously changing during several hours of use) but now it has become much worse (three or four encoders changing at the same time).

It does this "stand alone" out of the rack and not connected to anything, and I've done a memory reset. The switches all feel normal, and all work normally.

I took the top off, and I can't bring the effect on by physical disturbance of the boards. The only thing I did notice was that the encoder movements seemed less prevalent if I pressed down on the 50 pin ribbon connector between the front board and the main board, I cleaned the pins on the sockets, and things seemed to get better for a while, but then the problem came back.

I've order a 50-pin ribbon connector just in case, and will change that when it comes.
