Erratic Mouse Behavior When Docking or Resuming from Standby

ID: Q192845

The information in this article applies to:

Microsoft Windows 98

SYMPTOMS

If you move the mouse rapidly while the computer is in the process of resuming from a standby state, or immediately after docking or undocking a portable computer, the mouse pointer may begin behaving erratically. The mouse pointer may move in a direction and speed different from the actual mouse, windows and other objects may behave as if they have been clicked even if no mouse buttons are clicked, and other uncontrolled mouse actions may occur.

CAUSE

When the computer is resuming from a standby (suspended) state, the mouse driver may not synchronize properly with the mouse if the mouse is moved rapidly. As a result, movement information from the mouse may be misinterpreted as different movement or as button clicks, and button click information from the mouse may be misinterpreted as movement.
