Okay, this is admittedly a little obscure.
I have a standard Microsoft keyboard that includes 'media' keys - play/pause and volume adjust / mute. If Windows Media Player is open, pressing these keys triggers the appropriate action, even if the player doesn't have focus. This is good.
What's not good is if I have an mp3 file selected in windows explorer, pressing the 'play' button on my keyboard opens that file in Windows Media Player - even if the player is already in the middle of playing something else.
I only want to disabled the 'pressing the play key opens currently selected file in media player' functionality, not the 'pressing the play key makes media player play what's already in the playlist' - is this possible?
