PNS 4 lets you magnify and stare at four areas of the screen. When you open PNS 4, you see a Control Panel and four Display Windows. In Normal Mode, each Display Window shows a magnified and dynamic view of the screen surrounding the mouse; in Fixed Mode, each Display Window can monitor a fixed spot while you use the mouse for other purposes. There is an option to add crosshairs to the Display Windows. From the Control Panel you can Show or Hide Display Windows, turn crosshairs on/off, and choose each Display Window's Magnification (1.0 to 6.0 in 0.1 increments). Adjust settings, drag the Control Panel out of the way on the desktop, and click on the small triangle to make the Control Window smaller. Drag the Display Windows where you want (drag the sides or bottom right corner to change their sizes). Settings for the magnification, the locations of the Control Panel and the Display Windows, the number of Display Windows eand the Display Windows' sizes are saved between sessions. The Display Window menu item lets you set the number of Display Windows to show (1, 2, 3, or 4).
