If you reassign a mouse button to a different command, you may experience Shift key activation when you press the reassigned button while pressing certain keys on the keyboard. This is the result of the hardware information that is sent by the keyboard interfering with the software codes sent by the customized mouse button. To fix this problem, press the Shift key to disable the Shift key activation, and then do not press a mouse button while pressing a key on the keyboard.
The mouse may be dirty, which can impair performance. Try cleaning the mouse. If you are using a mouse that has an optical sensor or BlueTrack, make sure that you are using it on a surface that does not impair performance. The sensor performs best on surfaces with detail to track. It will not function on surfaces without visible detail (such as glass) or surfaces on which it has a reflection (such as mirrors or glossy surfaces). The sensor may also have difficulty tracking on highly repetitive patterns (such as printed magazine or newspaper photographs).
The Microsoft Mouse and Keyboard Center software is not supported on switch boxes. If you are using a switch box, some features, such as scrolling and reassigning buttons, may not work. To fix this problem, try the following:
Make sure that you install the Microsoft Mouse and Keyboard Center software on each computer.
Do not move the mouse when you switch between computers.
If the wheel and wheel button stop working, restart the computer.
If you experience other problems with the switch box, contact your switch-box supplier.
Some portable computers use a magnetic field to detect if the lid is closed. If your mouse has a magnetic charging cable, moving this cable too close to your computer may cause your computer to go into standby mode. To avoid this problem, keep your magnetic charging cable away from the portable computer keyboard.
If a rechargeable mouse becomes too hot while charging, the battery indicator light may still flash green, but may not charge. Refer to the Product Guide included with your device to determine normal operating temperatures.
