Copy both login and password not working

Hello,

when I try to copy both login and password, nothing is copied. It works properly if I try to copy the login or the password alone.
I already tried to delete all the cache files and also tried to make a new install. Tried many differents version, it's same. It worked before and it also work for my other colleagues which have the same configuration of mine.

Thanks for your help and sorry if my english is not perfect
