Remove Datasource from Crystal Report

I have a Crystal Report (Visual Studio 2005 standard) and change the data source at run time:
        crReport.SetDataSource(my DataSet)
        crReport.Refresh()
This has the identical structure as the dataset used at design time.  
The problem is that CR wants to open both the original and new datasets at run time.
I can't see any way to remove the design time data.  It does not show in the Visual Studio Data Sources panel, only in the Crystal Design database/database expert.

Thanks

Check this article on feeding your report from a data set
http://www.emoreau.com/Entries/Articles/2006/09/Feeding-Crystal-Reports-from-your-application.aspx

Also here is a document to show you how to change the data source.  I think it is on page 131.

If you want to change it permanently you can do it in design using
DATABASE --> SET DATASOURCE LOCATION
