I had the same problem. Turns out that the cord, where it enters the mouse, had broken. The reason I think was the constant bending due to not keeping the mouse and cord in alignment. Mine was routed around and through a crowded desktop and then down to the computer which sat on the floor. Replaced the mouse and keeping the cord straight resolved my problem.

Just offering this up as a possibility.

I am using Dell Inspiron 8200 and was using logitec optical mouse. never had any problems and all of a sudden mouse starts draggin to either top right corner or left bottom corner. I tried differnt mouse but was having the same problem. SO i unplugged the mouse and started using the touch pad but no LUCK. Anyonw with any suggestions?

Cordless mouse jumping and eratic ? Check the batteries 1st, most times it is the origin of your problem. Next get " Advanced WindowsCare V2 or similar program, since running this program I have no more "mouselag" Hope it helps you too !!

Using Dell Inspiron 8200/ Logitec optical mouse. At random pointer goes to right top, or left bottom and disappears. Not able to control. Same with mouse unplugged and using touch pad. Mouse/pointer starts working after a while, time varies. Sometimes returns to erratic mode.

I am using a keyboard and mouse set, the Microsoft Desktop Keyboard Elite and Intellimouse Explorer 2 to be exact.

There have been time when my screen, whether I was viewing webpages or Word pages and the screen kept scrolling down to the last page and staying there. The scroll wheel refused to allow me to scroll back up, nor could I use the scroll bar at the side of the screen to get back up. The system said my mouse was fine and batteries were fine.

Many F words later, plus a couple of C words, I picked up my keyboard to look at the serial number and the screen freaked out, I took the batteries out and tested them on a battery tester and all three were dead, I replaced these with brand new ones and the screen stopped being pyscho.

Sometimes it is not alway the wireless mouse, but the f****ing keyboard.

It seems that since I installed Service Pack 2, the on screen battery gauge for the wireless mouse and keyboard does not work with SP2.

I have the same problem as Mike! I have a Dell Latitude D600 and the touchpad and mouse(optical) both behave erratically jumping to the top Righthand corner or bottom lefthand corner at any given time! It is driving me insane? I do not think it is a surface problem? Are there any other solutions? I would appreciate any help?!
Thanks,

My iFeel Logitech mouse has worked great for years and suddenly started the jumping all over the screen thing. After reading these posts, I took a black textured flat receipt book and used it as a mouse pad. PROBLEM SOLVED! nO MORE JUMPING MOUSE PROBLEMS!

The reason thet cursor jumps all around has to do with Microsoft products running in the background like Outlook. The problem is, the application Outlook springs to life to check for mail. No big deal, but they do not do a good job of saving the current cursor pointer. I believe Iternet Explorer does the samething. Microsoft is not very user friendly, I.E. if not written by us, screw the other application. When I am doing something important that requires good mouse cursor control, I turn off Outlook. When Outlook is active, even in the background, the mouse becomes very cumbersome. Sometimes it seems to go, then gets stuck. You can really see this effect if play one of the card games, like solitaire which was written by them. They do not do a good job in the message passing from app. to app. to restore the cursor back to its proper place. That is why it seems to jump around. Not the driver, not the hardware, just that master of virus software developer MicroSoft.

My Dell optical mouse began jumping around erratically after my company gave us new, motivational mouse pads that contain the company logo and vision statement. It took me about two weeks to figure out the problem, and about two seconds to throw away the stupid mouse pad. My cubicle's laminate counter top works just fine.

can i use a blank sheet of paper instead of a mouse pad?
