Hello,
Since a couple of weeks I'm using an optical mouse (logitech
wheelmouse).
Eversince I use it, my cursor jumps over the screen every now and
then. It doesn't do it often and it took me a while to figure out it
was the mouse.
Yes, it also happens when I'm off line. I use adaware regularly, my
virusscanner is up to date, I use a firewall in highest security mode.
My OS is XP pro.
I've installed the latest driver.
Can anybody tell me if this is normal?
Is there any way to prevent this?
Thanks,

Sometimes the Logitech software will not reset the standard mouse
settings before it installs. As a result, prior settings of snap-to,
acceleration, rate, and left- or right-handed get stuck "underneath" the
Logitech driver which it cannot properly run with. So uninstall the
Logitech Mouseware, reboot into safe mode, check Device Manager that a
standard PS/2 mouse driver gets detected, then reboot back into normal
mode and ensure the PS/2 mouse driver is still being used. Then go into
the Mouse applet in Control Panel and ensure it is at all its defaults:
no accelertion, rate slider at middle position, right-handed mouse, no
snap-to feature, etc. Now install the Logitech software.
Of course, you never mentioned if you are using a cordless mouse. If
so, and in this order, hit the reset button on the receiver and then hit
the reset button on the mouse to make sure they are synchronized. And,
of course, you have already checked the batteries, right? I got so fed
up with having to replace the batteries after only 3 weeks that I know
have 2 sets of rechargeable NiMH batteries so one is already charged and
ready to go when the current ones get too low. The mouse can start
acting erratic long before they go so low that the mouse goes completely
dead. As I recall, NiMH batteries don't have a memory like NiCads, so
you don't have to stick the depleted NiMH batteries in a flashlight to
drain them to nothing before you can start recharging them.
Logitech recommends using the optical mouse on a light-colored surface,
but who wants to run their mouse across a piece of white paper? Have
you seen a mouse pad with a built-in gel wrist rest (I have to have one)
that isn't blue, red, black, or a dark version of those colors? The
best I could find was the Belkin gel wrist mouse pad that is medium gray
but even that's probably too dark and results in depleting the batteries
faster.
Could be whatever application you are running will not wait for the
mouse, especially in games. Check the mouse's properties in Device
Manager and see if upping the sampling rate will help to eliminate the
jerk within that application or game.
