Yes, indeed.
I was not able any more to reproduce the issue, so it seems that it is working fine now.
Just one thing: I have some “Save error” messages sometime.
I have not created a new ticket, because it is not recurrent, and the problem was always temporary till now.
Thanks for your help.
PS. Ravi de voir que vous parlez français, mais je crois qu’il est préférable de continuer en anglais pour que ce soit accessible à la plus grande communauté. 
Merci.
