Resolve problems with mouse button or scrolling settings

To resolve this issue, first visit the following Web site to download and install the latest IntelliPoint software:
If that does not resolve the problem, try the following methods.

Method 1: Select the correct Microsoft mouse and connect to a USB port

The IntelliPoint software tabs that are displayed depend on the mouse that is connected. For example, the Wireless tab is displayed only if you are using a wireless mouse.

1. If an IntelliPoint software tab that is appropriate for your mouse is not displayed, make sure that you have the correct mouse selected on the Buttons tab.
2. After you change the mouse selection, close the IntelliPoint control panel, and then open it again.
3. Try to connect the USB wired mouse or the receiver to a different USB port, and then check the behavior. By trying the receiver on different ports, you can eliminate any issues with the port.
   Note Bypass any port replicators, USB hubs, KVM switches, and so on, and connect the receiver directly to the ports.
4. Make sure that the name of the connected device is the same as the mouse that you are using.

Method 2: Uninstall any conflicting mouse software

If you have any other mouse software that is installed, such as Logitech or touchpad software, that software may conflict with your mouse. To uninstall software that may conflict, follow these steps:

1. If you have a Windows Vista or Windows 7 computer, open the Programs and Features item in Control Panel. To do this, click Start
   
   , type appwiz.cpl in the Start Search box, and then press ENTER.
   
   If you have a Windows XP-based computer, open the Add or Remove Programs item in Control Panel. To do this, click Start, click Run, type appwiz.cpl, and then click OK.
2. Follow the instructions to remove the software, and then restart the computer.
    

Note If you are using a laptop, install the latest touchpad driver from the manufacturer's Web site. For help, contact the manufacturer. For manufacturer contact information, visit the following Microsoft Web site:If the issue continues to occur, go to the next method.

Method 3: Perform a clean "boot," and then reinstall the IntelliPoint software

Step 1: Restart the computer by using a clean startup

When you start Microsoft Windows, other software may start together with the operating system. These programs may include antivirus and system programs that may interfere with your mouse. When you perform a clean startup before you start Setup, you prevent these programs from starting automatically.

For more information about how to perform a clean startup, click one of the following article numbers, as appropriate for your version of Windows:

Step 2: Remove and reinstall the IntelliPoint software

1. View the list of programs that are installed on the computer. To view the list of programs that are installed on a Windows Vista or Windows 7 computer, open the Programs and Features item in Control Panel. To do this, click Start
   
   , type appwiz.cpl in the Start Search box, and then press ENTER.
   
   To view the list of programs that are installed on a Windows XP-based computer, click Start, click Run, type appwiz.cpl, and then click OK.
2. Remove Microsoft IntelliPoint. To do this in Windows Vista, click Microsoft IntelliPoint, and then click Uninstall/Change.
   
   
   
    If you are prompted for an administrator password or for a confirmation, type the password, or click Continue. Click Yes to confirm that you want to remove the program.
   
   To remove IntelliPoint from a Windows XP-based computer, click Microsoft IntelliPoint, click
   Add/Remove, click Finish, and then click
   OK.
3. Restart the computer.
4. Reinstall the IntelliPoint software.

Method 5: Determine whether it is application specific

With newer “high-resolution” mouse devices, some applications may not correctly interpret partial scrolling messages. When low resolution wheels scroll up and down, the mouse driver sends a scroll magnitude of 120 for each tick of the wheel up and 120 for each tick down. According to the official documentation, a scrolling value of 120 (or -120) indicates one line of scrolling. If the application receives less than a full line, it should either scroll part of a line (which is what Microsoft Word and some other applications do) or if that’s not possible, save up the value until a total of 120 is reached (which is what Notepad does). Most current Microsoft mouse devices are designed to give a smoother scroll experience, so the wheels are higher resolution and send four times as many scroll events, but at one-quarter of the magnitude. So instead of 120, they send 30 (or instead of -120 when scrolling back, they send -30). This should result in scrolling at the same speed, just more smoothly.

Some applications may not handle this correctly.

For example, they may ignore partial scroll events, or they may interpret a partial (30) event as a full line (120). There have been instances of some applications that actually combine both of these incorrect behaviors. For example, some applications may ignore the positive partial events and treat negative partial events as a full line, which would result in slow scrolling forward and fast scrolling backward.

To test whether this is an application-specific problem, compare the behavior in that application to how scrolling works in Notepad or Microsoft Word.
