I have an oddity with the LCS application, and checking it appears to be the latest version available in the App Store. I have v3.2x19 according to the iPad.
When I'm running in yard mode, and the engine is idle, when I hit the shutdown key, the sounds shutdown, and the engine starts moving silently in forward.
When running in road mode, the throttle response is very flaky. I'm running an ERR equipped Lionel HHP-8 (stock, the 6-38402), and strange things happen. I can run along slowly changing the throttle and usually all is well. However, at times when I return the throttle to zero, the locomotive is still creeping. If I happen to move the throttle slider faster, the train frequently takes off at speed, and then when I reduce the throttle to zero, it keeps rolling along at a good clip! Even worse, the emergency stop button does nothing! I can honk the horn, etc. while it's out of control, but the throttle is totally unresponsive. I can stop it by changing direction, that returns the throttle to temporary sanity, only to repeat soon again.
Since the Bluetrain application has suddenly also developed this problem, what can be common? Is it, by chance, the 1.54 Legacy upgrade?
