no "#include <iostream>" ? I would not really on VTK objects to include
the necessary "standard" headers.

weird. Have you tried flushing the stream? I would imagine that a
newline should force the stream to be flushed but maybe something
awkward is happening that is modifying normal stream behavior.

Looks good to me, hopefully its a streambuffering error and the above
fixes it, although I doubt that.

Good luck.
