We have a revision control system for word 2010 documents. The system was written with VB 6 and used for Word 2003 documents. When revision level changed we use a different protection to the document. After upgraded to Word 2010, this system failed to work. For example, when change protection type from wdAllowOnlyRevisions to wdAllowOnlyFormFields, the application unprotects the document and then protect the document with new protection type. However, after unprotect the document and before call protect method, in Review->Restrict Editing panel of the document, the "Allow only this type of editing in the document:" checkbox is still checked. As the result, the document is not protected as we want through the code, but what set in the checkbox. Are there any VBA/Word functions we can use to programmatically clear that checkbox in the Restrict Editing panel? Many thanks!
