I had many problems with mine cursor, when I unplugged mine sound blaster, and this process starting with system, when i deleted all from Creative all back to normal.

Uses 1,352k on Win XP Home startup. Seems tied to my Creative Zen Vision W mp3 player. Seems ok to shut it off after computer is started.
