Sorry, I mean the osu cursor will not leave the osu window (also the edge of my monitor) while on menus and breaks and such. On version b20150619.1cuttingedge. I have to Alt+Tab to be able to move the osu cursor off the osu window.
EDIT: It turns out the update turned on the 'Confine mouse to fullscreen' option.
