Hi
I found another workaround, the NOWAIT clause

If I issue

REPORT FORM ... PREVIEW NOWAIT WINDOW {top_level_window}

it works and I can access preview toolbar

>Yes. The default ReportPreview.App form has trouble with trying to display itself inside a top form. It works - in that you see the preview form and toolbar inside the top form where you expect, but the toolbar is not available. I think this is a bug in VFP9.0, the unavailability of the toolbar.
