By Stephen Bucaro
Does your mouse work erratically, skip and jump across screen, or freeze up? Most problems with mouse are caused by dirt or miscalibration.
Clean Your Mouse
Most mouses (mice?) work by use of a rubber ball that moves three rollers. It is very common for rubber ball to pick up dirt and feed it into internal mechanism of mouse. Tame your mouse by giving it a good cleaning.
To clean a mouse, turn it over and remove cover that retains rubber ball. The cover is usually circular with groves that let you turn cover in a counter clockwise direction for removal. Remove rubber ball from housing, wipe it clean, and blow air into mouse housing. Inspect rollers to make sure they are free of dirt. Then reassemble mouse.
Jerky mouse movement can also be caused by mouse pad. Most plastic laminate covered mouse pads do not provide enough friction for mouse to track reliably. Cloth covered mouse pads perform much better, although they don't last as long.
Calibrate Your Mouse
If your mouse still does not behave, check it's calibration. Select Start | Settings | Control Panel, and open Mouse utility. In Mouse Properties dialog box, select Buttons tab and move Double-click speed slider control to set time between clicks that you want to be recognized as a double click.
Then select Motion tab and adjust Pointer Speed slider control to your preference. In Acceleration section, set None radio button, then click on OK button.
Check The Mouse Driver
On startup, Windows loads a virtual PS2 mouse driver that is contained (along with other virtual device drivers) in file C:Windowssystemvmm32.vxd. If another mouse driver is located in folder c:windowssystemvmm32, Windows will load that one to replace mouse driver in vmm32.vxd.
A second mouse driver, or other device driver may be interfering with PS2 mouse driver. Use Device Manager to troubleshoot errors. To access Device Manager select Start | Settings | Control Panel, then open System utility. Select Device Manager tab. In list of devices, double-click on Mouse. If there is an exclamation mark (!) or a red “X” on mouse icon, this means mouse has a problem. A PS2 mouse uses IRQ 12. Make sure no other device is configured to use IRQ 12, causing a conflict.
