Um... this is kind of tough to explain, so I'll post a video. But I'll try anyway: I'm not pushing any keys, not touching the mouse, made sure no keys were stuck down or anything. My beatmap list just keeps on scrolling on its own. Sort of like when you tell it to choose a random map, except... it's not stopping. It also occasionally selects another beatmap, and then just keeps going.
