Ive installed the latest, having this weird problem though! I've noticed some people having the same problems with the phone app, returning to desktop when the screen is 'unlocked' after the proximity sensor does its job, wich is now fixed it seems.. But for me, this occurs on ANY app :O (except the phone app it seems). It keeps returning to the desktop when unlocking the screen regardless of what app I was busy with or the method of unlocking. This is really annoying.. searched around but no results yet. Anyone got a clue?
