This shouldn't matter (eg. I don't think it will fix your C5 issue), but at some point I changed the order of that code. It should read:

with oPreview
    .oCR = this.oCR
    .oCReport = oReport

    This.SetPreviewWindow(loPreview)
 
    .PreviewReport(this.cReportName)
    .Show() && Crash
endwith
