Sometimes the mouse does not function properly due to a peculiar hardware problem. There could also be the possibility of the mouse being either too sensitive or slow, causing some misbehavior. There are some basic settings by which you can tweak the way Windows handles the mouse. Most of the tuning is particular to the PS/2 port that the mouse uses for connection. To improve performance or fix some issues with the mouse:
- Go to Start > Control Panel > System
- Under System Properties click on Hardware
- Click on Device Manager and go to Mice and other Pointing Devices
- Select your mouse that will be generally denoted as “PS/2 Compatible Mouse‘ or it can be a specific name if Windows XP recognizes the brand or model of the mouse that you are using. Double click on the mouse to open its properties.Select Advanced Settings tab under Properties
- The very first option, “Sample Rate” relates to how often the operating system determines the position of your mouse. If you want to increase the resolution of your mouse or increase the speed at which your mouse is tracked, you should increase this value. Increasing this value will make your mouse more sensitive and decreasing will make it less sensitive. Default value is 100.
- The third option, “Input Buffer Length” relates to the size of the input buffer that stores information about your mouse location. Increase this number if your mouse behaves erratically. Default value is 100.
- The last element is the “Fast Initialization” option. By default it is turned on in most cases. It basically increases or decreases the time it takes the OS to start up. If your mouse behaves erratically (moving in random directions or acting as though you have clicked buttons when you actually have not), clear this check box.
