I have a Kinesis Contour I've used for years, and periodically Macs will start to react to F4 like it's the play/pause media key on a laptop. That is, whenever I hit it iTunes opens instead of the application I'm using receiving the key press. I can't even try to bind it in my IDE, because it simply doesn't receive the keystroke.
I've seen various tricks for handling this on laptops with actual media keys, but I'm on a USB keyboard with typical function keys so they don't work.
Any ideas? Killing my productivity to suddenly have broken function keys!
