I'm not sure what you mean by this.  Could you elaborate?

The short answer is 'yes', the long answer is 'its complicated'.  I'll 
post code in a week or two and you can see what's going on for yourself.

No.  But maybe I should.  I'm still working out the most efficient way 
to do backtracking.  If you know any very efficient backtracking 
algorithms, please let me know.

Thank you for your feedback,
