I recently had my cordless keyboard/mouse combo replaced. Logitech sent a new one in Decemeber/07. Recently it has started to act up. When I'm typing it will all of a sudden decide it doesn't want to type all the letters or move when you hit the spacebar. If you keep tapping on the letter it will eventually type the letter or advance the spacebar. It also has a habit of zooming down to 30% when you hit a certain key. If anyone has any ideas as to what is causing this problem I would greatly appreciate your input. It is a Logitech MX-3200 keyboard/mouse combo.
