title: Flex Builder not building new source code
body: <p>I have imported an existing project into flex but any changes I make to the source are not being built and displayed when I test run the application. The original files which are in the bin-debug folder dont seem to be changing at all.</p>
  
  <p>I have tried cleaning the project, deleting the bin-debug folder even reinstalling flex builder, but nothing has solved the problem.</p>
  
  <p>I've read <a href="https://stackoverflow.com/questions/290768/flex-builder-3-executing-old-source-codes">this post</a> which was about the same problem but none of the advice helped.</p>
  
  <p>Any advice would be appreciated.</p>
