Query: Causal Loops and Collapse in the Transactional Interpretation of Quantum
  Mechanics   Cramer's transactional interpretation of quantum mechanics is reviewed, and a
number of issues related to advanced interactions and state vector collapse are
analyzed. Where some have suggested that Cramer's predictions may not be
correct or definite, I argue that they are, but I point out that the
classical-quantum distinction problem in the Copenhagen interpretation has its
parallel in the transactional interpretation.
