Analysis Workbook - Open Save Cancel pop up

Hi,

I am on BOE 4.1 SP3 Patch1 with Analysis for Office 1.4.5.1.  When I open an Analysis Workbook from the BI Launch Pad, I get a box at the bottom of my screen that asks me "Do you want to open or save xxxxx.sapaox (xxx bytes) from my.server.com?"  Open Save Cancel.  How can I stop this from popping up?

Kind regards,

Kelly
