My wireless mouse has trouble on the screen with the cursor being eratic and wavers about with nobody touch it as tho its got a ghost controlling it

Try cleaning the optical emitter and reflector of the mouse with alcohol.
Try disabling your touch pad and or touch screen. (Device Mgr.)
Check your mouse setting in Control panel (Uncheck the box next to "Enhance pointer precision"),
Calibrate your monitor

hi,use ana external mouse and go to device manager on control panel then check the driver of mouse and pad try to uninstall the driver then restart your laptop ,it should find the driver itself ..

You can change your setting for your mouse curson.
click on start, control panel, click icon mouse.
set your options as you want.
hope the pictures help. good luck : 0)

Do you mean your mouse icon is "ghosting" or "flickering"? That could be a graphic card issue. Install newest drivers for your graphic card (which can be found under control panel/Hardware if your a Vista user)
Or if the cursor moves on its own then the touch pad is damaged.

Try going to Start>Control Panel>Printer and other Hardware and look for mouse pad or something like that. I think the problem is that you can only use either the mouse pad or the mouse, can't use them both at the same time.

try reinstalling your mouse/touch pad drivers, if that doesnt fix, reinstall windows after u backup ur personal effects, if that doesn't fix, chances are its a physical problem, if you have the expertise, pop it apart and get to the mouse pad itself, usually built into the top, check to make sure the cable is fully pressed into the connection, then reassemble it and try again.

if all else fails, buy a new computer

Sounds like you have a touchpad malfunction. If its an older laptop, I would recommend replacing it. Not worth the hassle of trying to install a new touchpad...

Have you tried going into the control panel - mouse - pointer options - motion speed (slower) and experiment with pointer precision check box? Try it, see what that gets ya.

use a external mouse and see if the problem solves
if the problem solves then you will have to replace your touch pad.

If your cursor moves erratically on the screen (for example, if it jumps around the screen, moves at varying speeds, or selects items on its own), perform the following steps:

1. Clean the surface of the touchpad with a dry, soft cloth to remove grease, sweat, moisture, or other liquids.
   
2. Adjust the sensitivity of the touch pad:.
   
   1. Click the Start button and click Control Panel.
      
   2. Click Printers and Other Hardware.
      
   3. Click Mouse.
      
   4. When the Mouse Properties window appears, click the Pointer Options tab. (Figure 1)
      
      Figure 1: Pointer Speed
      
   5. Under Select a pointer speed:, click to move the slider bar closer to Slow.
      
   6. Click OK.
      
   7. Check to see if the touch pad still behaves erratically.
      
3. If the touchpad still caused the cursor to behave erratically, attach an external mouse to your computer and restart your computer. Use the external mouse to see if your cursor still moves erratically.
