Sonar Feature Leaves Rings on the Screen

• Microsoft IntelliPoint software version 1.0, 1.1, 2.0
• Microsoft IntelliType software version 1.0, 1.1

SYMPTOMS

When the Sonar feature in the Microsoft IntelliPoint or IntelliType software is active, rings remain on the screen after you select a window title bar or menu bar.

CAUSE

If the pointer is positioned on the title bar of a window and the right (secondary) mouse button is clicked, part or all of the currently displayed ring remains on the screen until that portion of the screen or window is redrawn. This also occurs when you open a dialog box or drop-down menu (for example, Help, File, or Edit) with the Sonar feature active.

This problem is not display driver dependent; it occurs with all display drivers, including VGA.

WORKAROUND

To work around this problem, either switch to another application to force Windows to redraw the screen, or disable the Sonar feature.

MORE INFORMATION

To select the Sonar feature, choose the Pointer Activity tab in the IntelliType Manager, or choose the Visibility tab in the IntelliPoint Tools & Controls. If both products are installed on the same machine, changing this option in one utility alters the setting in the other. Both products use mutual settings in the MSINPUT.INI file.

When this feature is enabled, pressing and releasing the CTRL key causes successively smaller rings to pulse around the mouse pointer, making it easy to locate.
