Uploading files Mime Type not correct for Office 2007 default extensions.

Question

hi all,
My company has recently moved over to MS Office 2007 and the default extensions for word, excel etc are now .docx, xlsx etc (ie xml based).
Unfortunately now when we upload files through APEX to the database the MIME TYPE value for these files isn't being recognised and not loadeding correctly into the APEX_APPLICATION_FILES table and subsequently any future retrieval of these files fails.
I could put some logic inthe up load procedure to look at the filename in APEX_APPLICATION_FILES and hard code in the releavnt mime types but this still causes problems when retrieving the content.
Has anyone come across this and got a workround? Is it a bug in AE?
regards
James
FYI - using APEX 3.0.2 over 11G.

I have not any response to my question and not sure if it is in Apex I need to look or the tomcat server that I need to look. I have a useful application to try to show others what Apex can do for our customers to collaborate. However, most of our customers are using office 2007 so, hoping this is possible.
I am using apex 3.2.0.00.27 if that helps someone to point me where to find more info on being able to have Word 2007 or excel 2007 fire up to open a .docx or .xlss file stored in a table blob column. Word or Excel does fire up to open .doc and .xls files.
The following is the query for a report selecting the filenames uploaded into a blob column in my table:
{ SELECT s.ID, SUBSTR(s.NAME,INSTR(s.NAME, '/',1,1)+1,length(s.NAME)) SHORT_FNAME, s.SUBJECT
FROM spp_attachments s
WHERE s.PROGRAM_ID = :P2_PROGRAMID }
Below is the stored procedure called from the link on the short_fname column in report query above.
{ create or replace PROCEDURE  download_file(p_file IN number) AS
v_mime VARCHAR2(48);
v_length NUMBER;
v_file_name VARCHAR2(2000);
Lob_loc BLOB;
BEGIN
APEX_APPLICATION.G_FLOW_ID :=245;
IF NOT (wwv_flow_custom_auth_std.is_session_valid) then
owa_util.status_line(404, 'Page Not Found',true);
return;
else
SELECT MIME_TYPE, BLOB_CONTENT, name,DBMS_LOB.GETLENGTH(blob_content)
INTO v_mime,lob_loc,v_file_name,v_length
FROM spp_attachments
WHERE id = p_file;
-- set up HTTP header
-- use an NVL around the mime type and
-- if it is a null set it to application/octect
-- application/octect may launch a download window from windows
owa_util.mime_header( nvl(v_mime,'application/octet'),
FALSE );
-- set the size so the browser knows how much to download
htp.p('Content-length: ' || v_length);
-- the filename will be used by the browser if the users does a save as
htp.p('Content-Disposition: attachment;
filename="'||replace(REPLACE(substr(v_file_name,instr(v_file_name,'/')+1),chr(10),NULL),chr(13),NULL)|| '"');
-- close the headers
owa_util.http_header_close;
-- download the BLOB
wpg_docload.download_file( Lob_loc );
end if;
end download_file; }
Thank you,
Mark
