Check Event Viewer logs for hints. Are you using XP's standard virtual
memory settings? When the pointer disappears it means that the mouse
driver has lost it's addressing versus the display line scanning. That
is something along the lines of a memory leak or similar in the mouse
driver used for that display. Event View should have some indication of
a system or application problem associated with this. I have a dual
monitor setup on a new desktop and I have noticed some similar squirrely
mouse issues if the monitors are set at different refresh rates. This
is a dual display ATI X600 adapter.
