opening .docx files with mc

[Jabba Laci <jabba laci gmail com>]

Hi,

I would like to open Microsoft Word .docx files with mc. I added the
following lines to my local mc.ext file:

regex/\.([dD][oO][cC]|[xX])$
    Open=(ooffice %f &)

However, after pressing Enter, mc enters in the .docx file which is
actually a zip file:

$ file test.docx
test.docx: Zip archive data, at least v2.0 to extract

How could I suggest OpenOffice for opening this kind of files?

Thanks,

Laszlo
