v1.0 Video playback on 2nd screen stops, while launching PR.

As title says, when I watch YouTube on 2nd screen and launch PR on main screen, the YouTube video stops (the picture hangs and stays), while sound of the YouTube video (flash player) continues...


Steps to Reproduce:

Watch YouTube on 2nd screen, start PR on main screen... (normal procedure)


Main screen Full HD (connected via HDMI), 2nd screen 1680x1050 (via VGA).
