The Kindle 4 uses metal dome switches for all of the buttons. When it registers a button press it takes a second before it actually acts on that press. Sometimes people press the button more than once while the Kindle is "thinking" - this will cause a page turn problem. So be aware of that.
If that's not your problem the next thing to do is a hard reset. Hold down power for 20 seconds or more to do this. When it eventually starts back up turn wireless on and then go to home, menu, settings, page 2 and change time.
If that doesn't fix it, either the switch has worn out or something's making the button stick a bit, causing the Kindle to think the button is being pressed again. Take some compressed air and try to blow out around the switch. You can also take some isopropyl alcohol or distilled water on a q-tip and apply it around the button. Let it sit for a few minutes, then blow it out. Repeat a few times. If there's something sticky stuck in there that usually gets it out.
If you still can't get it working the switch has likely failed. Unfortunately the switch is part of the logic board, as you can see [http://blogkindle.com/wp-content/uploads/2011/10/kindle-4-motherboard-back.jpg|here.] You can replace the logic board to fix. The part is available at [http://www.powerbookmedic.com/Amazon-Kindle-4-Motherboard-p-22864.html|powerbookmedic] for less than $4.
