Hmm. I don't have access to newsgroups from here, but I'll look into posting
that later. Thanks! :) And I'm actually running 2K with the latest
everything on it.. to the best of my knowledge.

Well it's good to be absolved of guilt. :) There is definitely something odd
going on. I gave it a chug through Purify and I guess the failed assertion
below is what causes the untimely death:

[I] Message: Assertion failed: pHead->nBlockUse == nBlockUse

... whatever that means. :) pHead.. I can remember someone in grade school
calling me that once...

For the interested reader, here's the last three errors..:
