My parents asked me to spy, or at least keep an eye on, my sister. The reason is personal, but is there anyway to check what my sister is doing and what is going on on her screen. Is there an application that will allow me to look at her screen from my screen. I am using a MacBook Pro running Mac OS X 10.6.2, and my sister's laptop is running Windows XP. I have access to her laptop, and we both are on the same wireless network.
