I have a IP 2010 filler form that we currently use to submit to two different document libraries (PDF & XML). This works great if the user has Office 2010, when attempts are made with Office 2013 no such luck. The behavior is very odd, the data connection appears to open (I can see the item in ULS logs) but the submission never completes. Its as though the connection hangs. Closing the form leaves and open INFOPATH.exe instance running in task manager.
However I've published this same form to a test environment and it works correctly in both Office 2010 and Office 2013. Any ideas?
Thanks
