Input Textfield with 1 Letter, dissapears on me

programming flash

Hi everyone,

I am trying to create a crossword puzzle made up of text fields, one for each letter. I am pretty much done, but there is one problem I can’t get a handle on. I hope someone brilliant can help:

The Problem:
The user has already typed a letter into TextFied “XY” and then clicks back into that same TextField (maxChars=1, btw.) to write over that letter (or not). I want the letter to stay until a new letter is typed, and definitely, if the user decides not to provide a new letter.

No problem, works 90 percent of the time. But sometimes --I find oddly enough especially with “S” and “D”, but not exclusively-- **the letter disappears and stays gone, even when you leave the TextField. **The Only way to bring it back is to go back into the Textfield and use the Arrow keys to move the courser to a position before the letter. Very Ugly!

This problem is triggered by clicking into the box as well as by the “stage.focus=” method. I already tried the setSelection- no succes, I also tried making the font smaller, - give it breathing room, so to speak- , also fruitless. Does any one have any ideas how that effect could be avoided with certainty? Here is my code for reference:


//my letterbox class
var inputFormat:TextFormat = new TextFormat ();

            var initCharacter:String="?";     
       
            inputFormat.font = "Arial";
            inputFormat.size=14;
            inputFormat.color=0x000000;
            inputFormat.bold=true;
            inputFormat.align="center"; 
            
            box.type=TextFieldType.INPUT;
            box.x=column * lbWidth + gridOffsetX;
            box.y=row * lbHeight + gridOffsetY;
            box.width=20;
            box.maxChars=1;
            box.defaultTextFormat=inputFormat;
            box.text=initCharacter;
            box.addEventListener(FocusEvent.FOCUS_IN, onFocus);
            box.addEventListener(FocusEvent.FOCUS_OUT,onFocusOut);
            
            function onFocus(event:FocusEvent):void {
                if (box.text==initCharacter) {
                    box.text="";
                }else{
                    event.target.setSelection(0,0);
                }
            }

//in another class, the crosswordpuzzle's  main class

function userInput(e:TextEvent):void {    

                var activeField=e.target;
                e.preventDefault();
                var Caps:String=e.text.toUpperCase();
                activeField.text=Caps;
               }

Thank you in advance for looking at this.
