When you using more programs, not just only BSplayer, then they can steal your focus - and then you have to click on the BSplayer window to ge the focus back.
Mostly happens when you using BSplayer on TOP and then fullscreen - when proggram steal the focus, you don't see a thing - BSplayer window are still on top - but the problem is, that BSplayer no-more react at your keystrokes, because they are going to be send to the other program...
How i can explain you more easily the fact, that this happens very often for me and lot's of others???
