inserting Word Files w/ saved security (read-only)

Hello, I have a database called document inventory (our document management system). I'm working on Windows, using FMP 6.0 (FMP 5.0 server) in a multi-client environment.

I am attaching word files into container fields, and all works well to retrieve these documents, except that the security access saved with the word file (requiring password to edit, or open as a read-only file) seems to be disregarded when the document file is opened through FMP.

Does anyone know what else I should be doing? I have experimented with both "linking" it and not, and either way seems to disregard the word security access I already saved in Word with the file.

Thanks in advance for any suggestions!
