excel messages appear behind the explorer screen

[Laura2]

I've published numerous Excel Workbooks and each of them have external links that are not required to view them. Therefore it produces a message when first opening the workbooks that reads "(The workbook you opened contains automatic links to information in another workbook. Do you want to update this workbook with changes made to the other workbook?)". This is not the issue. The issue is that this message appears behind the browser window instead of in front. The user is unable to close the browser to answer the question because it locks up as soon as the message appears behind the window.

Does anyone know how I can make that message appear in front of the browser window?

Thanks a bunch.
