title: PyDev-Eclipse Python not configured
body: <p>After forced restart due to frozen laptop (windows 7 pro, 32 bit) Eclipse is providing the following message:</p>
  <blockquote>
  <p>It seems that the Python interpreter is not currently configured.</p>
  <p>How do you want to proceed?&quot;</p>
  </blockquote>
  <p>Clicking the Auto config option and then ok I get the Python Interpreters window with the right name (Python), Location (<code>c:\Program Files\Python27\python.exe</code>) and system libs.</p>
  <p>It all looks ok but clicking OK or Apply doesn't seem to do anything and the whole thing starts from the beginning (the message about Python not currently configured...).</p>
  <p>I've checked my <code>.pydevproject</code> permissions and I have full control over the file.
  I also have dropbox sync-ing the project files but it has been ok for a while now.</p>
  <p>What is wrong, what should I check/do?</p>
