How to slow down the mouse's double-click speed in Windows XP
This page explains step-by-step how to adjust the double-click speed of your mouse in Windows XP. Many people experience difficulty double-clicking (clicking the mouse button twice in quick succession), because they are unable to do two quick clicks of the mouse button in time. The amount of time you have to complete a double-click can easily be increased to make the mouse more manageable.
Step 1: Open the 'Mouse Properties' window
Open the 'Start' menu by clicking on the 'Start' button, or by pressing the Windows key or Ctrl + Esc.
Click on 'Control Panel', or press C until it is highlighted and then press Enter if necessary. (Note: in earlier versions of XP, you will need to click on 'Settings' or press S first.)
You need to be in Classic view. If you see the text 'Pick a category', as shown in Fig 1, click on 'Switch to Classic View' or press Tab until it is highlighted and then press Enter.
Double-click on the 'Mouse' icon, or press M until it is highlighted and then press Enter, to open the 'Mouse Properties' window shown in Fig 2.
Step 2: Adjust the double-click speed
If it is not already selected, click on the 'Buttons' tab, or press Ctrl + Tab to cycle through the tabs until it is selected.
Under the 'Double-click speed' header, click on the slider next to 'Speed' and drag it to the speed you want, or press Alt + D and then use the left and right arrow keys to set the speed.
You can test the speed setting you've chosen by double-clicking on the folder icon to the right of the slider.
Click the 'OK' button or press Enter to finish.
