I've made two long lists and when I look at the contents with the 4*x table with the words

| Word ---- | W | D | R |

The W is there for all words, even though I ticked some off. But when I press the "Edit this section"-button the words are marked as I want them.
If I press twice on every word no (un-check->check for the words that I want to write, and the other way around for those that I don't.) no words get the "W" instead!
However If I do this procedure on only the ones the unchecked "W" these words get the correct state in the table.
(But if I do it on those which are alreeady checked, those aree removed from the table instead.)

So I tried it out some more. And any amount of checking and unchecking just toggles the Writing status in the end.

Found the bug and fixed it. Sorry that took too long, for a while this slipped under my radar. The fix will be uploaded soon.
