wow, melted the film? That's waaaay too hot, dude. Cameras need to be kept from freezing -- or at least really sub-zero temps -- and from getting much over 100 degrees on a hot day.
Never, ever, never never never leave a camera somewhere it can get as hot as yours did: Car trunks, inside cars on hot days, out in the sun and so forth. Hope the focusing eased up after the camera cooled down, but that sort of heat can do serious damage to lenses, melt oils and greases and so forth. If someone wants to put ur camera bag in the luggage compartment of a bus, say "no, that goes inside with me."
If you must go somewhere that hot, put the camera in an insulated lunch bag along with one of those plastic blocks of blue ice-like substance you can keep in your freezer at home until you need it. Or just put the blue thing in ur camera bag.
Ditto in really cold winter -- put a hand warmer in with the camera to keep it from freezing, or keep it under yur coat.
