eQuest Users Group,
The following is an error message we get on a particular project file that only pops up on the 1st energy sim run, not subsequent runs. The error also does Not pop up when the program builds the input files and you have the option to "pause on errors". The errors are:

ERROR: In E:\vtk2.3\Nightly\vtk\common\vtkPolyLine.cxx, line 208
vtkPolyLine (0x316A6400): normal and sPrev coincident

ERROR: In E:\vtk2.3\Nightly\vtk\graphics\vtkTubeFilter.cxx, line 190
vtkTubeFilter (0x316B6D00): No normals for line!

Does anyone have any guidance on resolving the error? The attached jpeg is how the error message pops up.
