Subject:  Thanks for finding a bug 
Author:  Joel Duffin 
Date:  Feb 12 2004 
I am a developer who has inherited the code for the Circle applet. I went and
looked and indeed, as Michael observed, the code contains a bug that is observed
as any sum over 18 being judged to be a completed circle. I've made a fix and
will post it in the next couple of days. I will post a message again when it is
available.
Thanks much!

Cynthia & Julee,
I just spent a while playing with the applet, and it appears to me that the
developers made an oversight when creating this applet. Instead of checking
whether the three numbers in a circle sum to 3, it checks whether the three
numbers sum to *at least* 3. There is a very big difference here. Try putting
3 numbers in a circle which sum to > 3, and you'll see that the circle gets
highlighted. I tried combinations on Julee's specific puzzle, and by my logic
saw no other possible solutions besides the one she gave, so it appears that the
0.8 is indeed a mistake. I feel fairly confident in saying that there's not
some other solution which uses all of the pieces correctlythe applet
creator(s) just made a mistake.
