In normal use it’s very minimal and not that bothersome (except I now have a ready made excuse when I lose at arkanoid 🙂 ). I’ll try later this night playing with it again, see if I can reproduce in the crash test mode.
This week end, I will install the arduino IDE, see if I can build the firmware myself, and maybe try playing with the code, see if I can get more details on what exactly is happening.
Thanks for the help 🙂
