I don't know if anyone else has this problem but I noticed that while I have been trying out the new ZW that the preview screen doesn't seem to be functioning properly.
When I load a song into the control section and click the "tick" to display on the main screen (which it does) it doesn't appear on the small presenter screen. I think (I don't have the programme running now to check) that when I format it (ie centre align the text) it then updates tho' I can't be sure. Hope this makes sense!
