Why Do Some Keys Not Work with Shift Key?
It seem like all of the keys on my small wireless keyboard work, including the Shift key. The problem is that many keys do not work when the Shift key is pressed. If I try to type a capital I or T, I get nothing on the screen. This keyboard is three years old, but it has hardly been used at all. When I began using it, quite a few keys would not work. Now it's just a few keys with Shift. Any ideas?
