[vtkusers] Re: vtkDecimatePro Bug + hanging

[Sebastien_MARAUX]

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.
