Does it seem like there's a ghost messing around with your mouse, causing it to move on its own and click things randomly? You might have an HP trackpad issue.
TouchStyk is typically the culprit here. You can enable and disable it on your own.
- Navigate to your Windows Start menu and type Control Panel, click to open Control Panel
- Select Mouse
- Go to the TouchStyk settings tab and click Disable, then click Apply or OK.
That should do the trick. If you need to re-enable it, you can perform the same steps above, but click Enable instead.
Sometimes that poltergeist's tricks can be treated with a driver update. Open a ticket with the Help Desk to start the exorcism.
