mrmr murmured in microsoft.public.windowsxp.general:

Win XP Pro.

I Shut down the bluetooth mouse that worked well when it was connected.

Got a MS mobile Mouse 4000 that has a USB receiver.

This mouse jumps and sputters part of the time. The other part of the
time it seems OK.

I only have one USB device, the MS mouse.

What is up with this ???

Could be one of a large number of things, like,

Radio interference

The USB receiver uses the same radio frequencies as your cordless phone
The USB receiver uses the same radio frequencies as a neighbor's cordless phone
The USB receiver uses the same radio frequencies as another neighbor's garage door opener
The USB receiver uses the same radio frequencies as another neighbor's drone which he uses to perv in windows
The next door neighbor's kitchen blender has no RFI shielding and generates radio interference when used
etc. etc.

Incompatible surface for mouse

Glass table top
Mirrored surface
etc.

Driver compatibility

Using "generic" drivers which only "kinda" work
XP drivers for wrong version of mouse or USB receiver
Drivers for wrong operating system
Drivers downloaded from a dubious third-party site


You got any more info about your environment which could narrow it down?
