I second the request for more details. How do you know it's your upstairs neighbors? Have you asked them? How do you know that they're reading off of your screen? If it is them, could they just be reading your screen through an hole in your ceiling? What OS'es have you tried? Is there a possible other explanation, such as screen reading software (e.g.jaws)?
