I created a password-protected .doc file in Windows yesterday using the latest version of OpenOffice (3.2.1)

Opening the file worked perfectly; double-clicked the file, OpenOffice popped up and prompted me for the password, then it let me edit the document as usual.

Tried it on another computer with Microsoft Word; worked perfectly as well.

For some reason though, it won't work in Ubuntu (10.10). I'll double-click the file, it'll open with OpenOffice and prompt me for the password, but once it opens it's in "Read Only" mode.

I tried it on another Windows computer, just to see if it would work, and it did.

I right-clicked the .doc file and looked at the permissions: (picture edited for privacy)



Every time I tried changing it from "Read-only" to "Read and write" it automatically (and immediately) switched back to "Read-only"

Does anyone know how to fix this?

Thanks
