Query: Was Satisfied - But Buttons stopped working

It is a great product. No complaints. Got used to the new shape pretty quickly. I don't have any problem with the space bar as such.Update 5/7/12: A few buttons stopped working on the keyboard abruptly (buttons j-k-l). I am yet to deal with the warranty/support stuff. Will update once I do it.
