Sorry for the delay in releasing 17.16 SE - I got tied up in my other life. A
couple of new items to report:
Crafty 17.16 SE has logo! courtesy of Dave (NoKetch@AOL)
Second - the quick test results: 19 problems solved but only 14 in the alloted
60 seconds. I believe the cutoff is artificial and considering that all 19 were
solved in < 6:30, I was very pleased.
