problem with volume adjustment and minimizing
i have a sony vaio Fs series. for some reason, whenever im running a full screen program, i.e. a movie or game, and i try to adjust the volume, it automatically minimizeds the program. this is really annoying. i dont think this is suppose to happen, and i've looked all over for the option to change it on my laptop, but i can't find anything. my brother also has a vaio laptop (S series) and his doesn't do this. can anybody help me?
btw: i have to press Fn and F3/F4 to adjust the volume.
