I am at wit's end here. I'm not even sure what kind of problem this is but I have had no luck finding answers thus far. When I press my backspace, spacebar, and enter keys on my laptop, they do not function as they should. For example, enter opens up a new firefox window. spacebar pulls up my printer window or types a few letters. Backspace opens up a window for computer only, duplicate, extend, and projector only. Does anyone have any idea what might be wrong here and how I might fix this? Nothing has been spilled on my laptop at any time. Thanks in advance. I really appreciate any ideas.
