Wireless Keyboard disconnects I am having a little trouble with my wireless keyboard.

In the past 3 weeks it has disconnected 3 times and then reconnected after a few moments. The Magic Mouse is working fine alongside it, and the power is up over 70%.

Any advice for when this happens or why this happens would be appreciated.
Mine did this for a bit - turn it off, pull out the batteries, and turn it on again. Failing that, un-pair it from your computer (ideally, pair it with something else too) and then re-pair - this solved my problem (although it was never as regular as yours).
