[vtkusers] is Vtk 5.2.1 64 bit clean?

Hi,

I have compiled VTK x64 version on XP x64 with Visual Studio 2005. I also combine VTK with 64 bit version of TCL and (since recently) Python. Most of the time my programs use more than 4 GB (once even 12 GB) of RAM. The last time I encountered a problem was about two years ago. If I am correct, this bug has been fixed in V5.0.2.

regards,
Leo.
