Now I only get issues when the users can't be bothered checking if their batteries are flat, ('isn't that what we hired YOU for?' :( ). I run the dongle up onto the desk and tape it down just in front of the keyboard. I bought a bunch of USB extension leads for here because I got sick of trying to track down wireless mouse problems. Bascially, look for sources of RF and remove them, or as Jonathan3056said, 'If you have a usb extension to plug the receiver into I would give that a shot'.

Also other similar wireless mouses with similar receivers can cause issues from time to time). Signal interference caused by nearby hardware (actually had an issue where the rear ports on the desktop were getting to hot and it was causing issues. Mouse surface area is messing with optics (too reflective, too bumpy, made of glass, too many designs under mouse sensor, etc) But for me the 3 common causes of a jittery cursor are: If you have a usb extension to plug the receiver into I would give that a shot.

Also - What mouse are you currently using? Could be an issue with them and might be noted on that manufacturers KB articles.

Does this mouse have any additional buttons/wheels that could be moving it? Have you tried disabling all but the left/right click?.

I know you have a dell optiplex, but I've also seen touch pads on a laptop cause craziness (You did ask for common causes).

Also note the 'enhance pointer precition' checkbox

Have you tried adjusting the mouse sensitivity in windows (Countrol Panel->Mouse)? Also, your mouse may have came with it's own software.

Have you tried different surfaces (ie: is a laminate table worse than a couch)? Sounds weird, but a mouse pad might help if it's the table surface.

If you pick it up do you hear any rattling in the air or does the mouse move (No I'm not messing with you to try, but it shouldn't move which could be a sign of a bad lense)

Could be a dirty lense on the mouse or bad lense.

Optical or Laser? - A laser is more precise and can cause more jitter.
