Abstract
A violation of gauge invariance in Witten's open superstring field theory has recently been discovered. We propose a modification which resolves this problem by avoiding the collision of picture-changing operators. Feynman rules for the modified, gauge-invariant theory are presented, including a useful representation for the Ramond propagator. All four-point amplitudes are off-shell finite, agree on-shell with the Polyakov approach and exhibit decoupling of spurious physical states.
