Analysis for Office - Prompt twice for parameters dialog box

Hi,

We are implementing Analysis for Office V1.4 launching workbooks off the BI Launch pad (BI 4.0 SP6.3) via OLAP connection to BW.   When running the workbooks directly from Excel with the Analysis Ribbon, everything seems to work ok but when launching via the BI Launchpad the report parameter prompt appears first, the user fills it in and the report refreshes however the user is prompted a second time with the same parameters.  If they hit cancel the second time the workbook loses its connection to the datasource.  The workbook is a simple single sheet, single datasource.

Any information on this would be greatly appreciated.

thanks,

Karen
