Started coding part2 yesterday...80% done. Finally decided on how to package part1 today and started coding it a while ago...90% done.
I expect to get it out before the weekend.
Have also more or less fixed the ideas for Challenges 43, 44 and 45.
41 is a prelude to 45...you must solve it ;)
Anyway you can take a break from it when 42 is out...
