General idea
Synaptics device drivers are used to meet the specific requirements of your device manufacturer. To ensure that you get the appropriate device driver, go to your system manufacturer support website to download the synaptics device driver.
No matter whether the driver for XP is downloaded in 3721, if the driver is not uninstalled, update the driver and the installer prompts you to restart the computer.
After the restart, check the driver and no changes are found. However, the scroll bar can be used in Firefox.
All of the above are experiences. I hope you can help me.
