Well.... First, I should tell you that if I use the keyboard that my computer manufacturer gave me, everything works fine.... However, when I use the wireless keyboard (which I bought from the store), then I have trouble... (The manufacturer's keyboard uses a wire, and is not wireless...) What I expect my wireless keyboard to do, is let my function keys work... For example, I did something to my computer a while ago, and I had to use safe mode to access my computer... As you know, you have to use one of the function keys to access safe mode.. I had to switch my keyboards temporarily, becuase I could not use the keys.... Do you understand what I am saying?
