i have the intellimouse explorer 4.0 and have erratic behavior, it stops moving-can't get it to move then it moves on its own where i can't control it. i installed a new one with the same behavior and can't figure out where the problem might be.
i installed the latest 6.3 software for it so that is up to date.
i also am wondering if the kvm switch that its connected to could be having a problem or be the cause.
i also have checked in the device manager and all is fine there.
Not sure, I'm loking under the compatablity section of a wikipedia page, first time I heard of a KVM switch. http://en.wikipedia.org/wiki/KVM_switch
Can't ne the mouse, the only reason it would fail is if the optical sinsor fails somehow and has to sync.
