I would like to have a pop-up window that is similar to a instant messaging window pop up at some point during my experiment. I am using this to create the illusion that the participant is actually working with someone and is getting feedback from them. Is there anyway to program this into Medialab. And would it be possible for the participant to enter an answer into the window when prompted to do so?

I would be unbelivably grateful if someone could help me with this
