My external pointing device works erratically on my laptop computer

If you can simultaneously use an internal and external pointing device on your laptop computer, you may find that the external pointing device works erratically, or that you lose the wheel and wheel button functionality.

To correct the problem, try the following:

• Change the system settings on your laptop computer to have the system automatically detect the external pointing device before the internal pointing device.
• If your laptop doesn't support automatic detection, try attaching your pointing device to the serial port.
• Manually disable the internal pointing device.

See your laptop computer manual for information about changing system settings.
