Especially when you hold a laser pointer...it never stays still.

The blood pulsing through your hand causes vibrations or shaking and changes in size too. So as long as you have a pulse, your hands, feet, face, everything will continue to move.

There is another reason.\n\nOnce this convention was set up, video game makers brought out optical sensing guns / pointers that would make use of this scanning feature to determine where the gun was pointed when the trigger is fired.\n\nBasically, these devices blank out the screen when the trigger is depressed, and start a counter. Since the screen has to be refressed from L to R and then the next row and so on, it can determine the time required for the screen to blank to the position it is aimed at. The controller then determines the position by interpolating the time.\n\nSince no one wants to break these devices by choosing any other convention, it stuck.\n\nThere may be reasons why it was chosen in the first place. The ray is actually moved by magnetic fields, and usually a ramp is used to generate this field. Therefore once it has moved to the right, the ramp is reset and the motion resumes from the left.

Check you haven't bent a pin on the video connection. That's the usual cause.\n\nIf you have, get a female to use tweezers (they're used to plucking single eyelashes etc and are more patient!)

move the mouse to the center and leave it there and they go away eventually

Happens to me alot too...I'v finally realized I need to double check before I start typing..Not sure why, haven't found out myself, but I do know if you click then make sure and click again, it will stay put.

It's a ghost.\n\nI kid.\n\nYou could just be getting interference from something around it. My wireless mouse will do that from time to time too.

Depends on what software you are using, what speed and if you are doing anything in the background. It's probably stuck but give it some time unless you have been waiting for an hr or more then give up on it.

this is beacuse every clock loses a few secs every few hundred years only laser precision fiber optic clocks dont as well it might be because of the boundary

You have way too much time on your hands.

MY HANDS ARE LIKE THAT TOO. WHEN I USE THE COMPUTER THEY REALLY GET COLD OR WHEN I READ A BOOK. AS LONG AS I KEEP MOVING THEM THEY'RE OK. JUST PART OF GROWING UP.

Try a mouse that plugs in to the USB port instead. They are really cheap.
