All of a sudden, I have "dead spots" on my screen where the mouse (pointer, touchpad, or external mouse) doesn't react. The cursor will still display in those areas, but I'm unable to click, so if a confirmation box appears in one of those areas, nothing happens and i need to use keyboard controls to get there.
Seems to be the lower right side of the screen (ThinkPad X220 laptop). Anyone seen this before? Any ideas?
