Version 8.4 > New Song Popup
Is there a setting that tells the new song popup to open on the Presenter Window instead of the Projection Display? Every time I install a new version this happens. In my current setup, I only have the projector on that display, so I have to turn on the projector to see the popup and move it to the correct monitor. And if I have to do some kind of edit in the service, this thing pops up over the program element instead of somewhere that the congregation doesn't see it.
Move the dialogue box to the correct monitor (you can often use 'Win' + '←' or 'Win' + '→' to move it between monitors, if it's active).
Then, while holding down 'Ctrl' on the keyboard, click the '×' to close the window. This will often save that window location.
