Random Certificate Prompts?

[bruderbell]

I'm running excel 2010. I used a smart card to access some work files (used the certificates on the smart card to authenticate on the SharePoint server), and now it seems that no matter what excel sheet I have open, I get random prompting via a dialog box to select a certificate. This happens even on a new, blank workbook.

Is there something I can do to disable this prompting?
