Hi there. My mouse is driving me mad. Reinstalled my PC. All fine. Installed MS Works - old version, I must admit - and I think it is after that that my mouse starting jumping all over the place and continuously "rushing" to the right of my screen. I cannot control it and am very frustrating. It is an old computer i am doing for a friend, using an HP PS2 mouse which I found in my box. Please help.
thanks
Christine

Sounds like its a optical mouse, and you are probably using it on a reflective surface ie plastic mousemat, glass or along that lines, you will probaby find out it works fine on wood, or a a solid surface that aint reflective or a gel mouse mat.. :-) all the best John

Stop my cursor jumping about


That must be a wire mouse the cable might be getting a bit frayed inside the sheath if it's a ball mouse, try taking the ball out and cleaning the ball and all the rollers. And if it is an optical mouse on bad surface. Put a piece of white paper on your desk and try it on top of that.

Jumping cursor of a


Hi! I think youre probably having a jumping cursor where the cursor jumps from one place to another while typing an email or something. You may got to control panel - hardware - mouse then look for the check box that you can tick on that says "Tap off while typing" and this should fix the problem. Thanks for visiting FixYa.com!

Hello,
The function Intersect from the CALCULATE menu finf the coordinates of a point at which two or more curves intersect.
To use it:
1. Draw the functions.

2. Press [2nd][CALC][5:Intersect]

The cursor is on one of the curves. Read the equation top of the screen. If it is one of the curves you want press [ENTER]. The cursor jumps to another curve (in this case the only other curve).
f75e725.jpg
Read the equation on top of the screen to verify thst it is the correct one. Press [ENTER]. The calculator asks asks for a guess of the coordinates of the intersection point.

As the intersection point is to the left of the current cursor position, use the left arrow to move cursor closer to the point.

Press [ENTER], and wait for the solution. Here it is.

In your question you talk about y intercept. If you want to calculate the ordinate of the point where a curve intersects the Y-axis, it is more efficient to use the [2nd][CAL][1:Value] selection.
0a11a73.jpg
You enter X=0 and press [ENTER]. The cursor jumps on the first curve (Y1=) an gives you the y-intercept.

Notice the position of cursor on graph. The y-value at the bottom is its ordinate.
To get the y-intercept of the second curve, leave the cursor on y axis and press the DownArrow. Cursor jumps to tthe second curve.
Since the X=0 is still stored, the value of y is displayed directly.

Hope it helps.

When I am typing he cursor jumps around


It is a fault with Lenovo laptops. My cursor jumps all the time, no matter what software I am using. It is NOT the 'sensitivity' of the touchpad, for my cursor jumps even when I am not typing, even if I don't touch the laptop! I can set the cursor to a certain point on a document and then, after about 30 seconds, it will just jump to another point, even if I am in another room.

Jumping cursor


First, try to adjust the sensitivity for the touchpad in the control panel for the mouse. If this doesn't work you can just plug in an external mouse to disable the touchpad. If it still jumps, read the following.

This will involve opening the top part of the laptop. Usually there is a plastic piece holding down the keyboard. Directly above the keyboard. Use a flat head screwdriver to remove it.

Once you see the keyboard, then remove it. Just below that is the connection to the touchpad, undo it and just tape it to an area underneath the touchpad.

Cursor jumps around


Does the cursor jump around when your hands are nowhere near the touchpad? The touchpads are heat and pressure sensitive. I personally have very warm (and sometimes sweaty) hands. I have this problem often when working on laptops. If I hover my hands over the pad, it causes the mouse to move. I've had to take a business card, put tape on one side of it, and use it as a flip-cover for the touchpad on most of my laptops. If the cursor moves around when you're nowhere near the laptop, then you may want to try disabling the pointing stick (if it has one). I've had several clients with laptops where the pointing stick mouse control go crazy and move and click on things.

The cursor jumps around the screen


Reposition your Wii so when you play you aren't pointing the controller toward a bright light (like a window or lamp). Bright lights freak out the controller. I have a huge window in the room with the Wii, and I have to wait until mid morning on sunny days or it's almost impossible to control.

Jumping cursor when typing


Since you have a logitech mouse, lets just disable the touchpad. You should be able to disable the touchpad via one of these methods:
  1. Look on the top row of keys. You should have one that looks like a little mouse. If you do, hold down the "fn" key in the bottom, and press the key with the mouse on it. That *should* disable the touchpad.
  2. Go to the control panel, and find the keyboard and mouse settings. Digging through the menus, you should find a touchpad. You can disable it through there.
