Annoying SVN behavior ": run 'svn cleanup' to remove locks (type 'svn help cleanup' for details)"

All starts out working fine, I'm chugging along and every thing is happy.
Then I get the working copy locked message, no problem just run cleanup. But
that doesn't work. What I end up having to do is to manually delete the
folder. This generally happens several time when checking out the entire
source tree.

Any Ideas ?

H:\bf\trunk>svn up

svn: Working copy '.' locked

svn: run 'svn cleanup' to remove locks (type 'svn help cleanup' for details)

H:\bf\trunk>svn cleanup

svn: Can't move 'Enterprise/apache2/modules/aaa/.svn/tmp/entries' to
'Enterprise/apache2/modules/aaa/.svn/entries': Permission denied
