  We measure the astrometric shifts of the light centroids for the microlensing
events in the OGLE-1 database. Of the 15 consistently detected events, 7 had
significant shifts which we were able to measure with a fair degree of
confidence. Those events with large shifts are also expected to be unresolved
with a background ``blend'', and thus, we suggest that we have identified
events in the OGLE-1 catalog which are strongly blended. Though we concentrate
on the OGLE-1 database, and use the DoPHOT package in order to perform our
analysis, we suggest that this shift is a generic effect, and should be
observable in any crowded field.
