kewl, just checking. often times this can happen to a guitar with a spruce top from shrinkage, and is pretty much impossible to fix once it starts.
here's a helpful hint I learned from Dan Erlewine. take a small plastic container (like a soap dish) and drill small holes through out. then place a damp sponge inside and keep it inside your guitar case. instant guitar humidifier inside the case. just don't over soak the sponge...
