title: Unable to solve flash error 5000: The class ... must subclass 'flash.display.MovieClip'
body: <p>I'm getting the following error on my flash project
  5000: The class ... must subclass 'flash.display.MovieClip' since it is linked to a library symbol of that type.
  I looked at the class and made sure that I import flash.display.MovieClip and I do. I tried to change the base class in the linkage to flash.display.MovieClip but I got the following message: "The base class specified is a native class and will be defined in the player at runtime. It cannot be edited."</p>
  
  <p>How can I fix this issue?
  Thanks in advance,
  Kfir</p>
