Query: String effects and field theory puzzles with supersymmetry   We investigate field theory puzzles occuring in the interplay between
supersymmetry and duality in the presense of rotational isometries (also known
as non-triholomorphic in hyper-Kahler geometry). We show that T-duality is
always compatible with supersymmetry, provided that non-local world-sheet
effects are properly taken into account. The underlying superconformal algebra
remains the same, and T-duality simply relates local with non-local
realizations of it. The non-local realizations have a natural description using
parafermion variables of the corresponding conformal field theory. We also
comment on the relevance of these ideas to a possible resolution of long
standing problems in the quantum theory of black holes.
