      var tlf: TextLayoutFormat= this.textArea.getFormatOfRange(null,beginIndex,endIndex);

     editManager.applyLink(value.toString(),"_blank");
      tlf["color"] = 0x18479B;

I've been unable to reproduce this in TLF 1.1 or 1.0. I wrote the following small application, based on your post. Can you look over it and tweak it and see if you can get it to show the problem? Also, are you using Flex 4.0 or 4.1? Thanks!
