Hi, this may seem like a basic problem, but on the K200 it is not! I removed the spacebar to clean underneath it and now when I try to place it back on it just seems very loose, loud and not very responsive. When I removed the spacebar there was a metal bar attached to it, I just left that there and reinserted the spacebar. The metal bar does not clip into the keyboard at all, only the space bar. Can anyone help me fix my spacebar?
