1 Create a project use flex sdk 3.4

2 Create a new mxml app Testadd.mxml

3 Add a source jpg Any.jpg

content of Testadd.mxml just two line.

  [Embed(source="Any.jpg")]

public var NotUsedSource:Class;

I think this just defined a class which represent some data. And I never use it or initialize any instance of it in this app.

4 Profile this app, when it is profiling I click the resize button of IE servral times.

5 From the profiled data a function named Testadd_NotUsedSource.flash.events:IEventDispatcher:dispatchEvent is been called

6 My question is why this function has been called.

I have the screenshot but can't add to this post.
