Ahoy there,
on the French keyboard in AZERTY, it is impossible to access the "1" key for renamed are pet because the "1" key is first an "&", even if we use Ver.maj to access the "1" the game does not consider it to be the right key to be able to rename your pet ...
So we need too switch On qwerty keyboard everty time when we need rename it
French keyboard :
The Number keyboard 1 un Numpad don't work too :)
