Hi Alex,
Thanks for the bug reports etc... I'm still completely overwhelmed
with work, family issues, and the book. I expect to simply stop
working on the book one week from today. That is the start of spring
break for Univ. of San Francisco and I will then start on the
software to get it ready for a full v3.0 release (for April?).
Sorry for the silence. I'm getting *very* close to finishing the book.
