When a user opens an excel sheet from her Outlook client, the excel sheet
stays minimized in the task bar and wont open until she selects it to open.
The normal behavior when she had opened excel in an email is that it would
open automatically (double click and then it opens) instead of minimizing it
to the task bar.

Anyone know what would cause this and how it can be corrected so that it
open automatically when she selects the file?
