title: SVN commit and checkout
body: <p>I commit my application to SVN (in which repository is stored in my external harddisk) in one PC (it commits "successfully" to be Revision 9).
  But somehow, when I checkout the same repository at other PC, it return "successfully" the older revision (Revision 7). </p>
