title: Eclipse fire up new Android instance every time you clicks "Run"
body: <p>One of my computer has the issue with eclipse and android SDK.</p>
  
  <p>Every time I clicks "Run" or "Debug", then the eclipse will open up a new android instance instead of refresh the app in the "opened" one. </p>
  
  <p>In the meantime, the console prints </p>
  
  <pre><code>    [2011-09-02 16:46:13 - Emulator] WARNING: Data partition already in use. 
  Changes will not persist!

  <p>P.S.  I have never get android properly working on this computer, but I have set another three laptops working well. They are all windows7 64bit machines.</p>
  
  <p>Thank you.</p>
