Flash CS cannot find fl.core and fl.video packages

This is just strange. I was trying to import the classes in fl.core and fl.video into a Flash project and the compiler gave a "Definition could not be found." error. Apparently this has been a problem since (at least) Flash CS3. The IDE does not automatically add those libraries to the classpath so you need to do it yourself.

Here are the instructions:

Open Flash
Go to Edit>Preferences>Actionscript>ActionScript3 Settings>

and add these two paths to the Source Path:

$(AppConfig)/Component Source/Actionscript 3.0/User Interface
$(AppConfig)/Component Source/Actionscript 3.0/FLVPlayback
