WEBUTIL client_to_db file transfer

Question

I cannot delete a file from the local client drive after using the webutil_file_transfer.clinet_to_db function, whilst the form is still running
-- CODE USED in Forms 9ir2
DECLARE
     result BOOLEAN;
     wordexe VARCHAR2(1000);
BEGIN
delete_check;
IF :ltr.datedl IS NOT NULL THEN
     lp_err_alert('Deleted letters may not be edited or opened.');
     RAISE FORM_TRIGGER_FAILURE;
END IF;
     COMMIT_FORM;
     result := webutil_file_transfer.db_to_client('c:\temp\'||:ltr.letter_id||'.doc', 'REF_LETTER', 'OLE_BLOB', 'letter_id = '''||:ltr.letter_id||'''');
     write_header_file;
     wordexe := 'C:\Program Files\Microsoft Office\Office\';
     client_host(wordexe||'winword.exe c:\temp\'||:ltr.letter_id||'.doc', 0);
     result := webutil_file_transfer.client_to_db('c:\temp\'||:ltr.letter_id||'.doc', 'REF_LETTER', 'OLE_BLOB', 'letter_id = '''||:ltr.letter_id||'''');
     IF NOT result THEN
          lp_err_alert('Failed to write document');          
     END IF;
     COMMIT_FORM;
     result := webutil_file.delete_file('c:\temp\'||:ltr.letter_id||'.doc');     
     IF NOT result THEN
          lp_err_alert('Failed to delete document');
     END IF;
EXCEPTION
WHEN OTHERS THEN
     lp_err_alert('Failed');      
END;
What I find is that the webutil.delete_file fails. If you try and delete the file using explorer you get a file sharing violation.
When the form is closed you can delete the file from explorer.
If I comment out the client_to_db line the delete file works ok.
Is the client_to_db leaving an object lock in the java functions?
Anything I can do about this?

Nigel,
I don't know the bug number, but I remember that this is a known issue with the pre-release of webutil that is fixed in production. Unfortunately I don't know whether there exist a work-around or not.
