  A recent article has employed the determination from groundbased images of
high proper motions in the Orion Nebula Cluster to argue that JW 349, JW 355,
and JW 451 are high velocity (38 km/s, 89 km/s, and 69 km/s, respectively) low
mass runaway stars. We report on measurement of the proper motions of these
stars using images made by the Hubble Space Telescope's WFPC2 imager and find
that there is no evidence for motions above 6.2 km/s for JW 349 and 7.9 km/s
for JW 355, while the motion of 5.5 km/s for JW 451 is only slightly larger
than the measurement uncertainty of 3.9 km/s. We conclude that there is no
observational support for these stars being high velocity runaway stars.
