Yes!
That's why it's not part of the official build. Please fix the errors 
and then send us your fixes :)

More seriously, there are are a number of problems with the class as it 
stands and nobody has had time to work through it and put it right. I 
weas sent some bits of code with some fixes for some of the problems by 
another vtk user who's name I can't recall right now- but I never had 
time to really sit down and get stuck in. If you'd like me to track down 
some zip files somewhere and send them to you so that you can have a go 
at getting the code up and running then please say and I'll get back to 
you off list.
