Word, OpenOffice and Connexions - probably part I

I have a word document with a few equations in it. When I open in OO2.4 some of them are read-only and some are editable. When I open it in OO3.0.1 all of the equations are read-only.

This behaviour is unchanged by toggling the settings in Tools->Options->Load/Save->Microsoft Office.

I'm running all of this on Ubuntu 8.10.

I really want to import the document into Connexions but the read-only equations don't seem to be a supported media type?

This is a placeholder blog post so I've got somewhere to attach a file while I look for a solution.
