Focus error for the foil change with arrow keys after a start

[perfektionix]

When WordsLive is started, then a portfolio or song is loaded, then a double-click on a verse is performed, and then the presentation view is switched to (via icon, function key or menu), the cursor keys do not work to change the verse. Only after the verse has been clicked on again, it is possible to change the verse using the cursor keys. The error will not occur again until the program is ended.
