Data Report Parameter Appears On Print But Not On Show

[moonbase]

Hi

I am setting some report parameters as follows:

With drReport.Sections!PageHeader
.Controls!lblParameter.Caption = NullStr(rsTable!Value)
End With

This appears fine if I print:

drReport.PrintReport

But not if I show:

drReport.Show vbModal

The show just shows the caption as defined in the report.

Is this some sort of timimg issue?

Thanks
