I was working on a project with another programmer, and there was this little "test" window and an icon that only showed up when you alt-tabbed to our app (it is a system-tray-only app). I simply assumed that the other guy knew about it and was going to take it out before release. Well, it stayed there for a long time, and the release got closer and closer. It finally got entered as a bug, and I asked the other developer "so you weren't going to remove it?" He said "I didn't know it was there. I don't really use alt-tab."
