So, I left my iMac alone for probably about 20 minutes and come back to it only to see that the computer looks like it has left clicked on it's own and I can't get it to let up, all I can do is drag my mouse around and highlight stuff on my desktop. I restarted my computer and now all I can do is right click. Needless to say, it's a pain because not everything can be right clicked. It's not my mouse, I've got 4 different mice in my house and all of them do the same thing. Anybody have any suggestions?
