Likely causes:

- Trackball stuck
- Make sure the battery is fully charged. Low or dead batteries can affect trackball movement.
- Turn off your trackball or unplug the trackball from the computer and try cleaning the sensor on the bottom with compressed air or a Q-tip and clean the trackball with a soft cloth.
- Move the trackball closer to the USB receiver (if you have a wireless mouse). If your receiver is in the back of your computer, it may help to relocate the receiver to a front port. In some cases the receiver signal gets blocked by the computer case, causing a delay.
- Reset the trackball orientation settings following these instructions.
- Keep other electrical wireless devices away from the USB receiver to avoid interferences.
- Unpair/repair or disconnect/reconnect hardware (if you have a wireless device):
- If you have a Unifying receiver, identified by this logo,
see Unpair a mouse or keyboard from the Unifying receiver. - If your receiver is non-Unifying, it cannot be unpaired. However, if you have a replacement receiver, you can use the Connection Utility software to perform the pairing.
- If you have a Unifying receiver, identified by this logo,
- Upgrade the firmware for your device if one is available.
- Windows only — check if there are any Windows updates running in the background that may cause the delay.
- Mac only — check if there are any background updates that may cause the delay.
- Try your device on a different computer.
