A few weeks back I was asleep and in the middle of a dream when a pop-up message(as above) jumped up in front of my dream. In the dream, I then opened MSN Messenger which opened to the right of my dream. I messaged a friend and told him that I was having windows pop up in my dreams. I then closed the MSN, selected Continue Dream from the popup and continued my original dream.
I’m going to have to install a Pop-up filter in my head.

PS. As I was initially designing the banner from scratch, I googled “Windows Error Message” to make sure I got the correct font and came across Atom Smasher’s Error Message Generator and saved myself an hour.
Man, the Internet’s got Everything.
