For some reason, every time I press and hold the Option key, my Display System Panel window opens. This is especially annoying when I'm copying files in Photoshop and it seems to happen regardless of which application I'm using. I've checked through all of my keyboard shortcut keys and modifiers and nothing else seems to be linked to the option key. Anyone have any idea what's going on or where else I should look? If it's helpful, I'm running 10.11.5 on a 5,1 MacPro with an Apple wireless keyboard. Thanks!
