Dynamic fonts don't work... but Arial and Verdana work

Hi,
I am trying to defeat my psychological block with dynamically loaded fonts in AS3, and I have an annoying problem. I am creating a clock with a textfield and I am loading fonts from a SWF library: the available classes/linkages are “Arial”, “ArialBold”, “MyriadPro”, “MyriadProBold” and “Verdana”.

This is the line where I get the class from the SWF, and it extracts the class correctly

clock    = new Clock( { fontClass: assetsLoader.getFontClass("skin", "Arial") } );


The constructor…

public function Clock(_clockProperties : Object) {
   Font.registerFont(_clockProperties.fontClass);
   
   clockFormat       = new TextFormat();
   clockFormat.size   = 20;
   clockFormat.color = 0xFFFFFF;
   clockFormat.align = TextFormatAlign.CENTER;
   clockFormat.font  = getQualifiedClassName(_clockProperties.fontClass);
   trace("FONT CLASS = " + getQualifiedClassName(_clockProperties.fontClass));
   
   clockTextField.multiline     = false;
   clockTextField.wordWrap      = false;
   clockTextField.selectable    = false;
   clockTextField.embedFonts    = true;
   clockTextField.antiAliasType = AntiAliasType.ADVANCED;
   clockTextField.type          = TextFieldType.DYNAMIC;
   clockTextField.width         = 200;
   clockTextField.height        = 40;
   clockTextField.defaultTextFormat = clockFormat;
   
   this.addChild(clockTextField);
   setActualTime(clockProperties.withSeconds);
  }

...

Now, if I use “Arial” and “Verdana” this works correctly, I see the clock, but if I use “ArialBold”, “MyriadPro” or “MyriadProBold” I can’t see anything, just the output “FONT CLASS = MyriadPro” that tells me that the font has been loaded.

Why do I see 2 fonts on 5?!

Am I registering the fonts in the wrong domain? I am loading the SWF with Greensock SWFLoader, specifying the loader context “new LoaderContext(false, ApplicationDomain.currentDomain)”
