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.
