The Microsoft wireless pointing device responds slowly to your movements, or the pointing device movement is inconsistent or irregular

When you use a Microsoft wireless pointing device, you may experience one or more of the following symptoms:

�	The pointing device responds slowly to your movements, to clicks, or to scrolling.
�	The pointing device movement is inconsistent, irregular, or "jumpy."

This issue may occur if there is a problem with electromagnetic interference from the monitor. This issue has been reported with an IBM flat panel monitor model 9495-AG1 that is using the 75 Hertz (Hz) refresh rate.

To resolve this issue, change the refresh rate on the monitor. To do this, follow these steps, as appropriate for the operating system that you are running.

Note See the product documentation for the monitor to determine the refresh rates that work best for the monitor.
