I stay in a 7 floor flat in South Africa. On every floor we have a camera installed in the passage. The images taken by the cameras are reflected on a monitor that is connected to a Hi Look decoder. There are many images on the monitor. The images for every floor should be horizontal next to each other. The problem is that the images shift sometimes to the horizontal line of another floor. When I use the mouse to draw a particular image to its correct horizontal line, it is not working. The problem is: How to get the images that they show in the correct horizontal line. As I said the mouse do not shift them. All I can think is that we must reboot or reset something.
