What's cooking?

Last week my wireless keyboard was acting up. With every keystroke it would type that character + an additional character. It was consistent, repeatable, yet still wrong.
I re-booted windows, that usually fixes half of my problems. Nope.
Move the USB receiver closer? Nope.
Plug it into charge? Nope.
Bake at 125 for 15 minuets? That did the trick!
Apperantly, leaving the window opens open all night while it rained 2 feet away is bad.
