Question about KEIO PS2 Optical Scroll Mouse

Erratic mouse behavior or my mouse has a mind of it's own

KEIO optical mouse m/n p816 driver version:5.1.2600.0 Microsoft 2001 system: AMD 2000xp+ 1gig ram 130 gig hd WindowsXP home SP2 recently updated dvd burner cdrw Nvidia gforce 5200 video card My Mouse suddenly started behaving erractically. Sometimes it just wonders around the screen at random in an erratic zigzag fashion other times it will zip across the screen in any direction. If I lift the mouse off of the desk to reposition it the pointer almost always shoots to the bottom right corner of the screen. It is also a wheel mouse and in some webpages when I am scrolling down the page when I stop to read something suddenly it scrolls very fast towards the bottom of the screen. I primarily play Everquest on this machine and the mouse does the same things when playing the game. I have removed and reinstalled the mouse driver several times to no avail. I have changed to an older ball mouse, to a different optical mouse and tried several other ideas that folks on other forums have posted about. This is the second time I have had this trouble. I don't remember what fixed it before, but I thought it was simply reloading the mouse driver. I havn't tried wiping the harddrive and totally reloading everything yet But I might.. someone posted in another forum that they did and it fixed things for a short time. I have ran two or three spyware programs as well as a couple virus probrams. (detection programs that is) My system seems to be clean from those annoyances. Any ideas? Thanks, Core

GO TO REGISTRY EDIT, FIND HKEY_CONTROLPANEL\MOUSE.

DELETE THE KEYS THEN RESTART WINDOWS.
WINDOWS WILL REBUILD THE KEYS.
IT MAY BE THAT YOUR REG KEY IS CORRUPTED.

If the mouse is optical, check the surface you're using it on. There may be some reflective property causing the trouble. If you have a laptop with a touch-pad, the outer area of the touch-pad may be causing the problem. Check for the build up of debris around the touch-pad border (under the plastics).

Try a new mousepad. the lazer reads even the fibers of mouse pads. even if it feels clean, it might be picking up on that.

Logitech with invisible optic After replacing battery, mouse became very erratic, sometimes moving, sometimes not. When "reset" is pushed it works for awhile then becomes erratic again.


Could be a bad batteries. I only use Duracell in mine, however, mine is a Microsoft. Also, check the manufacturers website for driver updates.

Mouse behaving erratically


1. uninstall the mouse and then reinstall the mouse by restarting the PC. Upon restart the mouse should be detected as new hardware and reinstall properly and this should correct the practice behavior of the mouse.
If not then you have a mouse with faulty electronics and needs replacement.

When this behavior is observed when using a Logitech product withinWindows® XP, it may be caused by a feature within Windows called"enhanced pointer precision". This feature may conflict with Logitech's software, causing the erratic movement. Enhanced pointerprecision became available in Service Pack 2 and therefore is notapplicable in any version of Windows® XP without Service Pack 2installed. For more information on enhanced pointer precision,please click HERE. If this link does not work, then you should go to Microsoft and search for Knowledge Base article 895550.

Please see these articles from the Logitech database for possible troubleshooting tips as well:
