Disable editable TextArea Component?

I have a TextArea component in a flash document, and this TextArea is loading text from a .txt file.

However, when you're viewing the textarea in a webpage, you can not only select the text that has been loaded into the textarea, but you can also delete the text written there, like it's a word document or something.

Is there any way I can disable this? I have scoured Google and haven't come up with any answers. Thanks in advance

myTextArea.editable = false;

Sorry, i've tried that and it doesn't work for this.

Argh my apologies, for some reason it's working now. I feel like such an idiot, thanks for your help.
