Began working on the parsing of the generated TEI code, and got as far as finding and iterating through all the <app> elements and finding their <lem> children, but then got stuck on getting the node value of the <lem> element. I probably have to get its text child element and use that.

Then I hit a severe problem with the GUI, which is very puzzling. All of a sudden, text areas don't scroll, even when full of text. I've tried everything to make them do so, but nothing works. This is a bit of a show-stopper, so I'll have to deal with it before I get onto anything else.
