We have an Infopath 2003 form that has been published to a Sharepoint 2010 library. Users are getting the error message below when trying to edit several of the forms in the library:
"This Form cannot be filled out because you do not have adequate permissions, another user has the form open, or the form is open in another program. Do you want to open a read-only copy of the form?"
Permissions are not the issue as they were able to create the form in the first place and another user does not have the same form open. The form is not checked out to the user. If I try to edit the properties of the file, I get the message that the file is locked for exclusive use by the user.
The form does use the solution for the Sequential Form ID and stored procedures for getting a form number. The form also has a custom task pane that includes a list of links to documents.
I'm not sure where to even start with trying to get this form unlocked and would appreciate any help you could offer. Thank you!
