Hi,

In this previous post talking about a bug with the Flex SDK, you can find how to fix a problem when you compile a SWF including a SWC containing pictures.

Actually the version of the Flex SDK is 3.1 and the structure of the java library slightly changed. I applied the same fix on the GenericTag java class but now this class is in the jar file swfutils.jar

You just need to replace this jar with the fix in this location:

/flex_sdk/lib/

Click here to get the jar fixed

Share and Enjoy!
