cross tab rendering issue in C Viewer V10

Hello,

I have created a cross-tab report in Crystal Reports 10 designer – lets name it “Test.rpt”. Our developers then use
Microsoft Visual Studio 2008 and create web form, place CrystalReportViewer control
with ReportSource property set to ReportDocument which been created using Load method (see code below):

---------------------
ReportDocument custReport = new ReportDocument();
String rptPath = Server.MapPath(“Test.rpt”);
custReport.Load (rptPath);
CrystalReportViewer.ReportSource = custReport;

----------------------

But any Vertical headers are rendered in-correctly (they show up horizontally).

Is there a known issue with crystal report viewer v 10 where Vertical headers are not processed
correctly?

Thanks
Rob
