I am using InfoPath 2013 and have created a test form with only one field, a person/group picker. If I configure SharePoint to open the from in the browser everything works correctly, but if I switch it to use InfoPath Filler the form will open but any attempt to look up a username by clicking the picker button will cause InfoPath to stop working (crash). The system error log has nothing useful and no other messages are displayed.
Searching on the internet doesn't turn up much beyond some tutorials about setting the default value to the current user. Has anyone ever had a problem like this? I am not a farm admin so I can't change settings at that level. Thank you
