Hi Hilary,
While I can open a read-only copy of Qdabra InfoPath to SharePoint List Tool.xsn in Design Mode, when I preview it I get the error "InfoPath cannot open a new form. The form template is not valid. The form template cannot be opened, because the system administrator has disabled opening form templates that require full trust."
Do I need to convince my security group that they have to at least allow Full Trust forms for developers, or is there a way to limit trust to the Qdabra form? Trusted Publishers? Trusted Locations?
