  We compute eigenmodes of the lattice Dirac operator for quenched SU(3) gauge
configurations on the 4-torus with topological charge 1. We find a strong
dependence of the zero modes on the boundary conditions which we impose for the
Dirac operator. The lumps seen by the eigenmodes often change their position
when changing the boundary conditions, while the local chirality of the lumps
remains the same. Our results show that the zero mode of a charge 1
configuration can couple to more than one object. We address the question
whether these objects could be fractionally charged lumps.
