For the last few weeks (ever since whenever the last change was made), two things:
I can no longer edit a word mid-session. I click on the ‘edit’ link, and it takes me to the word, but I can’t make any changes.
When I get a word wrong, and then re-type it, the answer is not snatched. I have to either type a space character, or hit the enter key in order to move on.
