the cursor sometimes moves upwards even when the mouse itself isnt being moved,what colud the the cause of these movment of the cursor.

Optical mouses [mice?] are very sensative to contrast between certain colours. If you are using a conventional mouse pad with graphics or ads on the face this can contribute to the phantom cursor movement.

Best solution I have found to prevent "Invisible Tony" from hijacking the cursor is to use a plain piece of paper as a mousing surface.

thanks for the reply.
Usually i dont us a mice pad,i just put it on my wooden desk,but i will try and use the white plain paper.

Also your mouse could be going bad. kink in wire etc... does it give u a slow response sometimes?

and make sure the mouse is nice and clean on the bottom

It is like having an infant - we often have to wipe their bottoms ;)



...before the optical mice we used to have to clean the mouse's balls :eek:

mice can be pretty hit and miss on wooden surface's aswell mainly dependant on whether the surface has a gloss "shiny" finish or not. The laser refracts off the surface giving the sensory reader a miss-interpretation of the mouse's actual position, thus u get the perception the mouse is moving of its own accord!!! simple soloution as mentioned.. use it on something with a dull surface e.g. paper, and non shiny stuff ;)

never heard that before. if there is a problem in a wire then it wont get recognised let alone running around his desktop. Some of the suggestions are really good and right that optical mice are very sensitve and we need to make sure the surface on which we are using them are clean (Static free).

I would suggest to clean the desk and also the bottom lens on the mouse. This should fix the issue.

Please let us know if that works.
