For a couple of weeks now, the feature "Copy source to target" has not been working well in my Editor. Most of the time, after clicking on it, the copied text disappears in a couple of seconds, and disappears again if I try another time. Sometimes it ends up staying, but most of the time, I have to manually copy/paste the content of the source segment into the destination segment.
Is this linked to a recent update of the editor? In any case, this is both annoying and undermining productivity.
