Strange, I have never heard of anything like that, guess you are all alone with that problem and nothing can possibly help you, not even reading the titles of the 2-3 bug reports that are at the top at the time you are posting. I am confident, this has nothing to do with the OS you are using or the keys that are affected, so just skip that information, maybe you just have to clean your keyboard more thoroughly, I suggest putting it into the dish washer. But I'm really really sorry you're having such an annoying bug - something like that would drive me crazy to the point of posting random cynical stuff on the forums and beyond.
