Thanks. I'll try that first if it happens again. If it resets but doesn’t fix it we know it's mechanical/electrical. But since pulling out of a pocket and then moving XY (but not actually moving) can break something I think I'll replace the cable anyway. I'll check the input diodes too. Likely not though. I'd think they'd permanently cause problems. I'll report back.
