I just got my first switcher. The only problem is, she is an EXTREME newbie with computers, so i would like to set the computer up for her. I cant go to her house because she lives kinda far, but can i take control of her iMac? I know you can, but on windows, i always have trouble with it because it never connects.. Is there any ports that i should open or something? I would like to just show her around like i was there, and this would allow me to do that.
