Can't Drag and Drop Anything
I've installed OS X Lion and now when I click on an icon on my desktop and drag it, it follows along nicely, only letting go of the mouse button doesn't drop it. In fact, nothing does. Instead the icon hangs onto the cursor as if I have kept holding down the mouse button. If I want to drag something to the trash, when I hover over the Trash icon and let go, it acts like I'm still holding down the mouse button and instead opens up the Trash folder. It's not limited to trash, it's just where I first noticed it. I can't move files between folders.
This pretty much happens across the board, too. Drag an icon off of the dock to remove it, it just hangs onto the mouse pointer and never goes away. Drag an icon from the icon bar at the top (command-click) and you can pick up the icon and move it, but never drop it. Is there a solution to this?
