Screen Brightness Icon Pops Up Unprompted
Hello,
I have a Mac Air that is not even a month old. Today, the screen brightness icon has started popping up as if I was hitting the brightness button on the keyboard, except I'm not. It'll go away, then pop up again several seconds later. I've tried restarting my computer, to no avail. It is driving me insane. I'm trying to work around it keeps getting in the way. Has anyone else had this issue? Why is it happening and how can I fix it? I tried reporting it as a bug but I can't sign in. The username and password fields don't work. Please help!!
MacBook Air, OS X Yosemite (10.10.2)
