[vtkusers] could you help me to find the wrong place?

[Jim Peterson]

when you say the program "will end up when I run it" does that mean it 
does not display a window? Do you get an error message or termination 
reason? Is the data actually XML? also, what version of vtk are you 
running, and what OS are you running on?
