How to stop Apache OpenOffice trying to recover files when starting?

Every time I start Apache OpenOffice I get a list of some files that it tries to recover. These files are no longer on my computer. How can I stop Apache OpenOffice from trying to recover files that no longer exist?

The File Recovery window that starts at the beginning of your session has a  Cancel  button. Click  Cancel . When asked if you really want to cancel the recovery attempt, confirm.
