This is an itsy bitsy tiny little problem that I doubt many people will encounter and probably won't cause any issues at all, but I've just noticed it and like a good open-source software user am reporting it to the devs.<br><br>Mac OSX Mavericks, OLP 2.1.3.<br><br>When displaying the screen on the primary screen (with no secondary screen added) and manual size/location put into the preferences (using x20, y20, 1024x768), and a song is loaded from the main interface, it displays fine. Then you use the arrow keys to change the slide or song and the screen jumps up 1 or 2 pixels.<br><br>Nice little odd thing for you to get your teeth into sometime when you're bored ;)<br>
