Confirming segments in Online Editor


When I confirm a segment in Online Editor and move on to the next one, it very often happens that the text I have just translated is not retained. I then have to re-type the same text and try to confirm it several times before it works. This is very annoying.

I have tried every combination (Ctrl+Enter, Ctrl+Alt+Enter, Ctrl+Alt+Shift+Enter) and it makes no difference. What is the problem?

Thank you in advance!
