  A test of quantum mechanics proposed by K. Popper and dealing with
two-particle entangled states emitted from a fixed source has been criticized
by several authors. Some of them claim that the test becomes inconclusive once
all the quantum aspects of the source are considered. Moreover, another
criticism states that the predictions attributed to quantum mechanics in
Popper's analysis are untenable. We reconsider these criticisms and show that,
to a large extend, the `falsifiability' potential of the test remains
unaffected.
