So I have no idea what just happend to my computer but when I was on a skype call, I opened Safari and went on Facebook and all of a sudden things got out of control. My skype call started appearing on Facebook and Facebook on my skype call and then my desktop went white when I tried to click on things and all my windows were appearing on top of one another. It lasted for about 5 minutes and then skype disconnected so I shut down my computer. It seems fine now... Attached are some pictures.
