I play the game in maximized windowed mode. I like it because I can easily move to the second monitor and read forums here for example.
However when I switch to another applicaiton, I still see the graphics but I don't hear the sounds anymore. Any suggestions?
Personally I always appreciated this feature. It's much better than having the mute the program every time I switch over. Honestly, though, I usually have the music totally muted and the overall volume at just below 10% anyway so I can have a show on Hulu or Netflix running without interruption.
