Finding Delphi Apps
This is an old trick. If you want to know if an app was written in Delphi. In the task bar right click on it. If the menu only has three choices: Restore, Minimise, Close then it is most likely a Delphi app.
This is not 100% accurate but it is right most of the time. There is a fix for it which is why it is not right all the time.
