OT doesn't auto-focus on 'next' button

[Glotzbach]

After a 'comment after answer' when in 'teach me' mode/tab/screen, after giving the answer by hitting enter, the button 'next' doesn't get auto-focussed (if that's the right word). The consequence is that you can't hit enter to go to the next word, but have to click next with your mouse. Instead, focus moves to the symbol section.

The button is also not reachable by using the tab key; the active area goes from the upper (screen title) to the lower (screen tab) tab button, skipping the content of the tab.
