title: Is there a compiler for Actionscript 3 on Windows?
body: <p>I'm working on an app that will run on desktops and mobile devices. I have Flash Professional CS5.  However, I am working on a project that really just needs AS3, and dealing with the complications of integrating AS3 with Flash has already taken a fair amount of time.</p>
  
  <p>There's a link that says "Free, open-source framework | Adobe Flex".  When I click on it it takes me to a page with Flash Builder 4.7 Premium for $700.  I'd rather have something free...</p>
