how to fix a persistent oo doc recovery warning?

[joe at actionline.com]

.
Every time I start Open Office, I see the following:

OpenOffice.org Document Recovery
Press 'Start Recovery' to start the recovery process of the documents
listed below.
The 'Status' column shows whether the document could be recovered.

I go through this procedure every time and every time it says
86C0F118d01 - Not recovered yet

And every time it says "recovery failed"

When I have searched for document 86C0F118d01 it the system reports that
document is locked here:

/home/joe/.mozilla/firefox/1x43npol.default/Cache/.~lock.86C0F118d01#

And when I go to that location and list all files, this is what I see:

-rw-r--r-- 1 joe joe     4496 2010-11-03 18:07 blocklist.xml
-rw-rw-r-- 1 joe joe        0 2010-11-04 09:36 .parentlock
lrwxrwxrwx 1 joe joe       16 2010-11-04 09:36 lock -> 127.0.0.1:+20600

What do I need to do to stop this from happening EVERY TIME I start Open
Office?
