[AS3] External Style Sheets

This is really frustrating me. I have an external style sheet, and it looks great, but it “flashes” the unstyled content prior to applying the style.

      private var style:WalkStyleSheet = new WalkStyleSheet();    //load my CSS  
            ...
            var locTextField:TextField =  new TextField();
            locTextField.styleSheet = style.styleSheet;
            locTextField.selectable = false;
            locTextField.multiline = true;
            locTextField.wordWrap = true;
            if (_isTestMode && !isRevealed) {
                locTextField.htmlText = "<p class='mediumBoldHeadlineLeft'>Click Here to Reveal Description</p>";
                textBoxContainer.buttonMode = true;
                textBoxContainer.addEventListener(MouseEvent.CLICK, revealDescription);
            } else if (isRevealed) {
                locTextField.htmlText = "<p class='mediumBoldHeadlineLeft'>" + _area[_areaIndex].location[_locationIndex].name + "</p>"
                                         + "
<p>" + _area[_areaIndex].location[_locationIndex].description
                                         + "</p>";                
            }
            locTextField.height = 275;            
            locTextField.width = 350;
            locTextField.x = 35;
            locTextField.y = 375;
            locTextField.name = "locTextField";
               textBoxContainer.addChild(locTextField);
