OK lately my keyboard is not responding to all my keypresses as fast as i would like. Alot of times i must stop typing and retype something because the keyboard is missing my keys. This is also happening when i play games, it will not let me walk (in fps games) and i have to press it several times to get a reaction. I have just put in new batteries so it might not be the batteries. Now i really like my mouse and the keyboard and mouse are both wireless and came together (logitech). Could my keyboard issue be solved or do i have to buy another, and if so can i still keep my mouse which is also wireless.
