press U > game > check the Lock box
It's a shame but other then locking it and do what the gm said, is your only option.
Locking the skillbar never stopped stuff from moving around for when It would happen to me.
set the skills as you want and exit the game normally. click the exit and wait for the game to close completely.after that they will be saved.
you're force logging too much. force logging in middle of pk does more harm than good
