I get the runaway problem now and then and it's not connection related, it's software for sure. I get it sometimes when doing a star allignment, it just keeps going after I release the arrow button. I've found changing the slew rate while it's running away stops the mount, but pressing an arrow key starts the runaway again but at the new slew rate. Pressing the enter key when the runaway scope passes over the alignment star stops it and calibrates it.
I tend to calibrate if shooting east and recalibrate if shooting west. The first cal may or may not run away and the second cal may or may not run away. There is nothing repetative in it at all and I can't foresee when it will happen. I've just learnt to live with it
