Hi Ian,

Glad the QFS business seems solved.  Thanks for that bug report.

Again, good eye.  I was using the value of the initial guess as a
logical flag to choose between the initial value and the best fit
value as the value to display.  An initial guess of 0, of course,
evaluates false, thus it would display the best fit.  That's just a
silly programmer error and will be fixed in the next trial release.

I will look into this, but not today.  I was in a meeting since 9
am... :(
