Hi again
Your describtion on how to solve my problems, sounds more like the way
I've learned to do it

So far I've tried almost everything, except the car box, which I will get
very soon, but nothing has helped. But she is still very young (4 months)
so maybe it'll get better over time.
I am of my studies (summer vacation) for the next month, so I have lots
of time to train with her, so I hope, I will see some progress there

There has been a bit progress, but after a few days, everything goes back
to her normal behaviour... Can't really understand why, since there has
been no change in our daily routine.
Thank you to you all, for inputs to my problem.
Regards,
Deborah
