Apple Duo 270C manual There are ghost images or black dots on the screen

There are ghost images or black dots on the screen.

nWhen the computer is left on for many hours, temporary defects may appear on the screen. Put the computer to sleep. The longer the computer was left on, the longer it will take for the images to fade, but they will eventually disappear.

The pointer moves too fast/too slowly.

nYou need to adjust the pointer’s tracking speed. Open the Mouse control panel and choose a more comfortable setting.

The pointer won’t move at all.

nA software problem may have caused the computer to “freeze.” Restart the computer by pressing the Command (x), Control, and Power On keys simultaneously. You will lose any work you have not saved.

A window has disappeared.

nAnother open window on the desktop may have covered the one you’re looking for. Move, resize, close, or hide windows you aren’t using until you see the one you want.

nWindows belonging to open but inactive programs may be hidden. Choose Show All from the Application menu to show hidden windows.

An icon is blinking in the menu bar.

nOne of your programs needs attention. For example, you may have set the Alarm Clock to go off at a particular time, or PrintMonitor may be alerting you to a printing problem. Make the program active and take the necessary action.
