When a user "chooses" a file, save its name somewhere. When another user chooses that file now, check and see if it's in your "list". If it is, tell them it's checked out, otherwise check it out for them. Be sure to implement a "timeout" feature so files cannot stay checked out indefinitely (unless you want that). ---John W.
