Isn't it that setting ThisForm.oCrystalApp = .NULL. will only ensure that the reference to the object is destroyed but not releasing the actual object instance itself?

I really got some problem here because there's no such .Release() or Close() or Quit() method in the Crystal Report Application object. This is not the same case like Word.Application or Excel.Application objects where there's a Close() / Quit() method that could be invoked to destroy the object.

Thanks again for all your quick reply.
