Hi all... I've got a simple problem with my D200. The release catch for the pop-up flash sticks in the open position so that every so often, the button on the body is stuck flush and recessed. With my finger, a light touch sets it free and back to its normal "ready" position. I was thinking that a very little bit of WD-40 would clear this up in a heartbeat... I was thinking I'd spray a little puddle's-worth and use a toothpick to apply about a drop to the release catch. But, do think that's wise to do? Not that I think this would void a warrentee, but do you think there's something critical under there that might get dripped on if it leaks into the body?
