I fixed problem #1 below. It will be in the next patch. If you are building your own binaries, the fix is in the CVS 2.6 branch. I did not experience problem #2. I will try to reproduce it today. Did anyone run into a similar problem?

Also, I get no ghost cells so when I extract an isosurface the process boundaries are clearly visible. I place the Clip Filter at roughly 45-degrees (eyeballed, not much precision) so that it gives me the lower-left half of the data, and when it crashes I get a trace like the following:

</span><br></div><br clear="all">If I load the same ImageData Dataset & apply the D3 filter, then attempt to use the Clip filter, it works. I have alot of rendering artifacts (I think due to the Structured->Unstructured conversion) and it takes ALOT of memory, but it works.
