Closing project properly

[Gugge]

Hi!
Im using borland c++ builder and having problem with the X in the right top corner in the forms. I have a multiple form project and have made it that way that when the user closes a form (using my TButton 'EXIT') another one pops up. But if the user uses the X the form closes, but then there still remains forms hidden, which is disturbing. Can I some way control the X as an Object?
