[vtkusers] What's wrong with me?

[Amy Squillacote]

Hi Jenny,

Please be more specific about the problem you're seeing.  What 
breaks?  Does the program seg fault?  If so, please include a stack 
trace.  Does the program run but produce results you aren't 
expecting?  If so, please explain what you expected to happen and how 
that differs from the behavior you see.  Also, if this problem could 
be platform-specific, please describe the platform: OS, compiler, 
anything unusual about the hardware, etc.
