In this latest update, I am no longer able to have the selected game's artwork not replace the launchbox background. I prefer it to just use the default background even when a game is selected. In the "Default Background" section, I have "Use LaunchBox Default Background" selected, and I unchecked everything in "Background Priorities" but I'm still getting a blown up cover for my background when I select a game. Unchecking all the background priorities adds a checked blank item to the list when I reopen the options, as shown in the attached image.
Edit: Actually, it's not always using the cover image. Just seems to be a random image from the selected game.
