Ghostly film's name

[daniela]

I'm desperate! About five years ago I watched this film about a young girl who is a ghost, and every night at 10 o'clock at night she appears in a class cloakroom, and re-lives her death. One night a boy who was locked in the cloakroom by his friends sees the girl ... so he helps her find her murderer. I need to know the film's name or even just the name of an actor who was in it ... I'd be very grateful ... thanks.

That sounds like Lady in White (1988). The little boy was played by Lukas Haas, who was also the little boy in Witness.
