Hi. I'm finding (since 3.3.7367) that, if I leave MB opened in the background, not playing any music and whilst I'm busy doing other things, when I return to it, it has become totally unresponsive. I have found I can get around this by switching to compact player from the task bar, at which time MB now responds, and then maximising it back to full screen. I find this to be a bit bizarre; MB obviously hasn't crashed as I can eventually restore it without closing and re-opening it, I just can't bring it into focus when clicking on it normally.
Just me, or this a known problem?
