Well... There is something about changing batteries.

Of course, not everybody has a contract with the Ghostbusters, but if you open the hood and take the battery away: well... they can just go away, those nasty creeps.

Seriously, I had the problem for the first time last Saturday, changed my battery and the problem was gone (OK: for now). Repetition not guaranteed.

NB: If my Avatar was stuck; we used to practice the so-called 10 cm method: lift the (heavy) thing 10 cm and then drop it. Should not work, but it did.

There are no wrong answers, but there are different perspectives.
