SYMPTOMS

After you enable the Enhance pointer precision feature in Microsoft Windows XP Service Pack 2 (SP2), you may find that the mouse does not track as smoothly as it did before you enabled this feature.

  1. Click Start, click Run, type control mouse, and then click OK.
  2. Click the Pointer Options tab, click to clear the Enhance pointer precision check box, and then click OK.

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.

MORE INFORMATION
