Illegal override of z in mx.core.BitmapAsset

When embedding images into a class you can often get the error below:


Exception fault: VerifyError: Error #1053: Illegal override of z in mx.core.BitmapAsset.


to avoid this error from re-occurring you simple have to check the version of the flash player that you are running. In my case I was running flash player 9 and complying to 10 so I just point the flash player path to flash player 10 and it worked.
