Not loosing focus

Hello, I'm writing a chat, and want to make written text selectable but not editable, this is the code I use:

 int a = 0;
 ArrayList Buffer = new ArrayList();
 
 foreach (string Entry in Buffer){
     GUI.TextArea(new Rect(10,10+(25*a),Screen.width / 1.11f - 20,25),Entry);
     a++;
 }

I have already tried to save the current focus before adding a new line(GUI.TextArea), and restoring it later, but it doesn't work properly, if you are writing a message it will select the whole text and when you keep writing it erases it.

Thanks.
