Oven door doesn't shut tightly

[karenjude]

I just noticed today that our oven door doesn't shut tightly. There's a small gap when it's "closed". If I push on it, it closes tightly but won't stay that way unless I hold it. There's nothing in the way that is preventing it from shutting. Is there some type of adjustment I can make to have it close correctly again?

Check to see if the screws that hold the bottom hinges on have come loose.
