>I want to preview a form from a single Document Interface but in the EXEcutable this preview don't appear. I prove to open another form and display preview in it ( form xx preview window ...) but this form is opened two times, and I have to close manually the first (the second contains the report preview).

This is a bug in VFP 5.0. You need the main screen to be present. As I understand it, this has been fixed in 6.0.
