I made my first attempt at an Infopath form today - user A fills it out from
the SharePoint site and hits submit, which sends an email to user B.  The
problem is that when user B tries to open the received form, he is asked to
put his smart card in the reader.  Once he does this the form opens properly,
however I would like for this step not to be necessary.  
I tried setting the option to 'always use this account' under 'Manage
Credentials', but that doesn't seem to have helped the issue.  Can anyone let
me know how I can get around this?

Thanks,
Tara
