Small n factoring

[Nuri]

Keroberts, is it working properly now?

If not, would you consider a copy-paste of the contents of your prime.ini file, some sample rows of the working pairs from the worktodo.ini and fact.txt, and some sample rows of the non working pairs from the worktodo.ini and fact.txt files?

May be somebody can guess what's going wrong (if it's not hardware related, of course).

BTW, you should note that if you're using only one or two PCs, expect it to take at least a year to slim down 15m-16m to 999.
