When I'm using iPhoto, the hard audio buttons on the keyboard (previous, pause, next) no longer apply to iTunes. Suddenly, they do things in iPhoto instead. Things like play and pause slideshows, start slideshows, work like arrow buttons, etc.
I dislike this.
Is there any way to keep the hard audio buttons being used for iTunes while I'm in iPhoto?
I'm using iPhoto 9.6.1 on Yosemite 10.10.1.
For various compatibility reasons, I'm unable to upgrade to El Capitan or the new Photos app. (I don't know if that would help me, but anyway.)
