*1 -- what session was the report listener created in?

The ReportListener is on the form, I guess it's session must be the form's session.

*2 -- what session is the report data in ? (could be the form's session, could be private, could be a different one, could be the same as #1, might not be)

Private

*3 -- what session is the private FRX copy in ?

I don't know. I know that the ReportListener runs it's own session, but I don't know how to acces it.

*4 -- what session was the report launched in ? (could be the same as #2, might not be)

The form's session, which is private

Anyway, the problemn is over with the old NOCONSOLE (sorry that everybody thought that this was a serious problemn, I thought that myself)
And thanks
