Hi all, I am using an aftermarket power supply with Carrera D124/132 and the Control Unit 30352. I am having trouble with PC Lap Counter (the newest version). Sometimes, when stop is pressed, the race restarts on it's own after you "ok" race end. I'm not sure if this is a CU problem or a problem with having the aftermarket supply. I have a Carrera 18v Digital power supply and have no issues using that.
