There was a time when my mouse worked fine, But then it began to make movements on its own. The mouse pointer moves to the very right of the screen, while it is there I can move it up and down and even right click to bring up a menu but i cant seem to move it left. There are times when the Mouse reappears somewhere on the screen and then moves to the right and disappears. As of now I am having to navigate with the keyboard.

I have used Spybot in the case that it is spyware that is causing the problem but it recovers no immediate threats.
Have any of you suffered this problem?
If so could it possibly be a virus that is causing this or an undectectable spyware program? Can u Recommend any free programs? Help!!

Is this an optical mouse in use with a shiny mousepad by any chance?

Life is more painless for those who are brainless.

i doubt its spyware or a virus or the like. If its optical, which I assume it is, have you tried cleaning the eye with compressed air or something? also try different surfaces, including no mousepad, to see if that makes a difference.

Hi, Sounds more like the mouse has a problem with the horizontal movement sensor. Can you borrow another mouse and try it?

Good Luck, Jim

If this is a corded mouse, it is common for individual wires to break inside the cord, usually right where it enters the mouse,
after the mouse has been used for some time, or sooner, if the cord has been abused e.g. by yanking on it. At first the insulation on the individual wires will hold the broken ends together some of the time but the connection is poor and you will have intermittant problems, or even bizzare behavior of the movement of the cursor, or it will click on things on its own. When the insulation breaks and the wire ends separate, the function of that brokem wire will not work.
You can often confirm this condition by moving the cord right where it enters the mouse - if the insulation is still intact, it may behave ok when it is in some positions, and misbehave in other positions.

If you're handy you can remove the cord sheath near where it enters the mouse, find the broken wire(s), and solder the ends together or splice in a new short length, and/or open up the mouse and move the repaired portion inside the mouse such that the cable sheath is clamped properly.

Hey, (My mouse is cordless btw)
I just tried to push the cord in and move it about and it seems to be working again. If it goes haywire again I will maybe try to take it apart. Then again it is probably best to just buy an optical one.
I really appreciate all of your suggestions and thank you for all the help guys.

HUH?

"Then again it is probably best to just buy an optical one."

Mice with balls will last a long time if the cord wires don't break - they just need occaisional cleaning.

If your mouse has a ball, the mouse tends to accumlate crap on the two roller bars and the roller wheel inside the mouse where the ball contacts them - when enough crap has accumulated the cursor movement of your mouse will become erratic. You don't need to open it up completely. Remove the trap door and the ball and clean the crap off the three places the ball touches - methyl alcohol (wood alcohol, gasline antifreeze) or isopropyl alcohol (rubbing alcohol) on a Q tip works well, or a bit of water on a Q tip works less well, and/or you can gently scrape it off with something small - avoid making scratches on the roller bars and wheel if they are plastic. Clean the ball too if necessary, but usually it doesn't need it.
Rarely, that isn't enough. The roller bars are on the same shaft as a wheel that a sensor detects when it moves and that tells the mouse it's cursor position is changing .
Sometimes dust or fuzz or hair gets in between the wheel and the sensor, and you must open up the mouse and get rid of the mung - usually blowing it out at a hole in the wheel's / sensor's enclosure is enough, but you may have to remove the roller shaft and wheel.

Keep your mouse pad, or wherever you move your mouse around on, free of loose dust, hair, crumbs, ashes, etc. and you won't have to clean the rollers as often. If your mouse pad is dirty, clean it, or get a new one.
