  During the OGLE-2 operation, Soszynski et al. (2003) found 3 LMC candidates
for an RR Lyr-type component in an eclipsing binary system. Two of those have
orbital periods that are too short to be physically plausible and hence have to
be optical blends. For the third, OGLE052218.07-692827.4, we developed a model
of the binary that could host the observed RR Lyr star. After being granted
HST/WFPC2 time, however, we were able to resolve 5 distinct sources within a
1.3" region that is typical of OGLE resolution, proving that
OGLE052218.07-692827.4 is also an optical blend. Moreover, the putative
eclipsing binary signature found in the OGLE data does not seem to correspond
to a physically plausible system; the source is likely another background RR
Lyr star. There are still no RR Lyr stars discovered so far in an eclipsing
binary system.
