Hi there, it is also happening to me this evening. Tryied to Push two times and both times, once after releasing the Barke and Chocks, once after the end while setting the Brakes, i slid forward and began "Flying". It did not make a difference if i had the Chocks on or off. Just for Info: It was not on purose to check, soley out of coincidence.
