Hi,  
Flash CS3/AS3 has many weirds behaviors!  
The first one is the error message “1151: A conflict exists with definition dummy in namespace internal.” when I create a MovieClip Box and put a movieClip Circle inside it.  
When I declare a public var circle:Circle on Box, I get this message.

So, what´s the right way to put symbol inside symbol?
