Dear Bruce,
I realise you may be travelling soon ,
This is not a very serious bug as I have work rounds.
I was demonstrating linear combination fitting in Athena using the gold thiobacteria example this week.
I am using 9.25 on a windows 7 computer.
I read in all the data from the cynaobacteria project file
I mark  5 or 6 standards
In the LCF tab
I  use marked groups, untick the sum weights to 1 option leaving just the all weights between 0 and 1 option selected.
I pick a sample spectrum eg 4.73
I select fit all combinations
It rolls through them  and reports the apparently correct results but an error message is reported:
Redundant argument in sprint at C:/...  /AppData/Roaming/DemeterPerl/perl/site/lib/Demeter/UI/Athena/LCF.prm line 780, <F> line 122

Clicking any of the answers in the combinatorics tab brings up this error again.

If I  do a fit of lot of spectra using  the same set of standards, I get a similar  error message except this time it is line 906 and some of the combined spectra don't plot properly until you refit them as a single spectra in the standards tab

I attach a log file but not a project as I assume you can find that on github!
