I can't pin down when this started happening, but I believe it might be 12.13 onward. I've noticed sometimes when I try to open an emulator within BB using the option ("Open Xenia", etc), the window will open in the background for some reason. I have to alt-tab to it. It does not always happen, and it doesn't appear to be with certain emulators in particular. I've also noticed it when I open the folder for the game. It seems that opening any window seems to happen in the background. Not sure if it's LB related or not, but didn't have that issue in the past.
