It's the Dell Dock. I uninstalled it. & for some reason, it just takes awhile (like a minute or so) for it to realize that right button = right-click. Even stranger is sometimes when it starts up, it can only right-click, even though I'm clicking the left button. But that's most likely the laptop itself.
I wonder why they took away the feature that'd let you look at multiple windows at once & made the show desktop button so hard to find (yet nice & out of the way).
