I seem to have encountered a whole new issue with this upgrade to 1.70r2. I carried out the upgrade yesterday and was quite pleased when all went well and I didn’t get any of the problems that others have found. However, that all changed today. On start up I got the on screen message “setting points” - my points didn’t set so I assumed that the box had been unchecked – not so, the box was checked, so I tried to change the points – nothing happened. All locos and carriages with lights would run on the track until they came to a point or crossing, then they would trip the circuit breaker protecting the track. It was then that I discovered that the circuit breaker protecting the points and crossings had already been tripped, although I couldn’t find any cause. I was advised back in June last year to install these circuit breakers by DCCconcepts to overcome shorts on points / crossings. https://www.hornby.com/uk-en/forum/electrofrog-point-misbehaving/?p=3/#post-253686 The only thing that has happened since yesterday is the 1.70r2 upgrade I installed 1.69 but this made no difference.
