mmm, are you sure the mouse is Vista compatible? If not that is why you are having the jitteredness. Also check to see that the mouse as a full battery, and that the adapter connected into the PC has a gd connection, and isn't hanging out.
For Halo 2, check that you are running the latest patch, and check that your gfx card has the latest drivers installed.

If the mouse problem persists, take it back to where you purchased it from and ask for a replacement. If you bought online, e-mail their customer services and give them a nice complaint! :P

Have you got one of those converters that change the USB to a PS/2 connection?
If you are going through that, it may solve the problem, seeing as you are using the PS/2 stnadard connection and not a USB one requiring drivers. Worth a try.

Mice tend to work best on Vista and Win7 with native plug-and-play drivers. The problems often begin when using the 3rd party drivers and apps supplied by the 3rd-party vendor.
Try uninstalling Logitech's SetPoint and driver package (drivers may need to be uninstalled via device manager.
After re-boot, plug the mouse back in and allow Windows to install native drivers. Let us know if this helps :)
