Problems downloading docx files seen as zip

    For info - Software in use:-
    IE7 and IE8 RC1 and Office 2007 installed on Windows XP SP2 clients
    IIS 6 on Windows 2003 Server R2
    Firefox 3.0.7

    I have seen a lot of comment about this problem but no definitive solution
    so far, so I (and others) would be extremely grateful if anyone has the big
    picture on this one...

    I am trying to set up an IIS installation that provides Office 2007 docx
    files, however there is an issue when downloading the files. After clicking
    on the link to the docx file IE shows a dialogue box offering to open or save
    the file, however it sees the file as a "Compressed (zipped) Folder".

    Clicking on Open shows a second dialogue box with only the options to Save
    or Cancel the download which is now correctly identified as a Microsoft
    Office Word Document. More confusingly the lower half of the dialogue box
    contains the following text (I've paraphrased a little here):- "File cannot
    be opened by the default program. It is either corrupted or has an incorrect
    file type".

    Trying the same operation in Firefox results in the expected behaviour, i.e.
    Word 2007 opens with the document loaded.

    The server mime type for docx files is
    application/vnd.openxmlformats-officedocument.wordprocessingml.document which
    I believe to be the latest/correct value.

    The XP clients have the correct file association, i.e. if you double click
    on a docx file, Word 2007 opens with the document loaded.

    I am aware the docx format is compressed XML, I just don't understand why
    IE7 (and IE8 RC1) seems, to my mind, to be mishandling the request that
    Firefox manages successfully.

    Our internal company standard for the web browser is IE so I don't really
    want to have to change to Firefox across the entire organisation and it is
    not acceptable for this application to save the document to the desktop and
    open it there (which does work BTW) since the end-users will be enquiring on
    hundreds of these documents every day.

    Many thanks in advance to anyone that can help.
