I think we solved the issue. Recently, we have done quite a lot of testing in order to catch the issue. Today we finally managed to reproduce the behavior you ran into. To make the story short, we found out that every time the program was started (WORD 2010) or we created a new document, WORD created it as an old .doc document (Compatibility Mode) and we were unable to add Docentric elements. So, after saving the document into one of OOXML formats (.docx, .docm, ...) the problem disappeared.
Explanation: The Docentric elements are just ordinary content controls which are not supported by the .doc format. And this is the reason WORD won't let you add Docentric elements when in compatibility mode.
After searching the WORD 2010 options we found the option:
File -> Options -> Save -> Save files in this format
which was set to "Word 97-2003 Document (*.doc)".
I suspect that you might also have the same value as we had (".doc") for the setting. if this is the case you probably have to options:
- either change the setting to ".docx" (see the attached picture), or
- save each new document as .docx before you start editing it.
Please let us know if this solves your problem.
