Just purchased a ornata about a week ago and today I noticed hitting shift + z will not capitlize the letter. Shift + any other letter or number works fine only the letter z. Both shift buttons have the problem. The z key works by itself but I am having to press caps lock if I want to capitilize it. Is this a setting I can turn off? Ive searched everywhere and have had no luck. Or do I just have a faulty keyboard? It seems odd that every other key works but z. Thanks.
