I am using Windows 2K with VTK 4.0
standard build for windows.
more precisely it hangs saying it cannot
read memory at address xxxxx. So
I guess it is an allocation problem.
The other problem is that it doesn't
care about error settings, maybe I
should try CVS / nightly version ?
Sorry for html mails, I wasn't actually
aware of it and didn't think about
pine and other small mail clients users.
