@pgklada: We are working on the player right now, so I just went to a video (a long one, since I thought that would make it easy to reproduce this bug... http://channel9.msdn.com/Events/Build/2012/1-001) and I can't get the progress bar to stop working (I tried smooth streaming *and* progressive, dragging and clicking to reposition) ... can you give me some more specifics of the video you were watching and what you did to make it 'dead' ... and perhaps exactly what you mean by 'dead' ?
