i’m in trouble for a very strange situation:  
a)i’ve create a movieclip as a symbol that movie clip is called “dina\_barra” and linked as “barra”.That clip contain an other symbol, a movieclip called “base” and named as “mybase”.  
A class is defined corectly in dina\_barra and here correctly registered.  
(so everything work ok)

b)all is stored in the library.

c)on the stage i use an instance of “dina\_barra” named “mydina\_barra”

running my movie happen that:

a line of code inside the class registered for dina\_barra:  
\> trace(mybase.\_width);  
return an UNDEFINED value… the same with trace(this.mybase.\_width)…  
in some cases it work but return the root clip width…?  
HOW can be possible?
