To get straight to the issue, whenever I press a key like shift or ctrl, it sticks. Not physically, but it acts as if the key is still pressed. So if I were to press shift then let it go, it acts as if it is still pressed and will capitalize the next letter I type even though I am not pressing it. I then have to press it again or even twice to 'unpress' it. Any ideas on what the issue could be? Thanks for any help.
