Question Why does my mesh-name show up as ProcName in output? 

Forum: Biasing and Scoring

From: Stefan E. Mueller <Stefan E. Mueller>

In my macro-file, I declare several meshes to score "doseDeposit":

/score/create/boxMesh mesh_DA
/score/mesh/boxSize 52.5 2.5 0.025 cm
/score/mesh/nBin 210 1 1
/score/mesh/translate/xyz 0. 0. 578.445 cm
/score/quantity/doseDeposit Dose_A
/score/close

/score/create/boxMesh mesh_DB
/score/mesh/boxSize 52.5 2.5 0.025 cm
/score/mesh/nBin 210 1 1
/score/mesh/translate/xyz 0. 0. 652.095 cm
/score/quantity/doseDeposit Dose_B
/score/close

/score/create/boxMesh mesh_DC
/score/mesh/boxSize 52.5 2.5 0.025 cm
/score/mesh/nBin 210 1 1
/score/mesh/translate/xyz 0. 0. 725.755 cm
/score/quantity/doseDeposit Dose_C
/score/close

To my astonishment, I find the name of the last mesh ("mesh_DC") as the name of the last process
 (the process after which a particle's track ends) for particles like heavy 
ions, muons, positrons (particles I'd expect to decay), e.g.

The coordinates are nowhere I'd expect the mesh to be, nor do the other meshes' names ever appear in the outputfile.

Is this the expected behavior of GEANT4.10? Did anybody else observe a similar phenomenon?
