Sometimes when starting a map, osu doesn't register taps and as a consequence it's impossible to hit any notes. You can hit the ends of sliders (and get 100 points) by having the button held down, but the initial tap goes unnoticed. I think this is some kind of anti-cheat thing, because every time it's happened in the past it's been when the game has lagged or the music has gone out of sync.
Also, the focus stealing "feature" is still there, and it is as annoying as ever.
