Do you have laptop mode on ?

I've seen similar reports of pizza guys doing the same when delivering pizzas.
Funny thing is that I've had a friend report to me that this started for her the moment she put her computer in laptop mode and then went away so I wanted to know if this is a common factor.
That is a strange one, I'll play for a while with laptop mode on (despite being on desktop) and see if anything is amiss.
This happened to me as well. I am not in laptop mode. It doesn't happen all of the time or with all of the stalkers, erm, visitors, but I have had it happen too.
This happens to me alot too, and I am playing on a desktop PC.
Thank you for all the reports. So not related to that. Good to know.
