Hi Jeff,

I created a small test project with one Top Level form and run your code from a button on it. VFP desktop didn't show up, only Top Level preview window.

>* Get a reference to the preview container API
>  Do (_ReportPreview) With oPreviewContainer
>
>  * Set preview container API properties
>  With oPreviewContainer
>    .Caption = cCaption
>    .TopForm = .T.
>  EndWith
>
>  * Create the report listener object and assign the preview container object
>  oReportListener = NewObject('ReportListener','_ReportListener')
>  With oReportListener
>    .DynamicLineHeight = .T.
>    .ListenerType = 1
>    .PreviewContainer = oPreviewContainer
>    .QuietMode = .T.
>  EndWith
>
>  Report Form (cReportName) OBJECT oReportListener NOWAIT
