[Paraview] ParaView 3.8.1 hangs on select points/cells for plugin-generated multiblock data set

Tue Dec 7 11:11:04 EST 2010

Hi Takuya,

Thank you very much for that feedback! I managed to compile ParaView
git/master for Windows 32/64-bit in the meantime and indeed, the
reported problem is gone with that version such that your and my
plugin(s) work smoothly again.
