Sounds like you have a faulty electronic connection in that part of your keyboard. MSRP is only 19.95 so replace it or send it back for repairs if under warranty.
So my Microsoft comfort Keyboard 2000 worked fine for about 2 months. Then, they keys between Left Shift and B stopped working. Also, the Escape key doesn't work. Then, miraculously, they started to work. Then, out of no where, after a day or two or working, they stopped working, again. Anyone posses any clues?
'c' is set to my paste function, but it's kinda hard to get by without the others. Thanks, bros.
