Sharepoint page with a Webpart with a ReportViewer control

[JASV]

Hello!,

I have a sharepoint page (MOSS 2007) with a webpart to an aspx page (VS2005).

The aspx page includes a ReportViewer control that display a SSRS report.

When I click over a plus icon for a drilldown inside the SSRS report, the
page jumps to locate the top border of SSRS report on the top border of the
browser window.

Do you have any recommendation to avoid this behavior?.

Thanks you
