Re: [Jython-users] Help with broken code

[Rafael B. <be...@hs...>]

First of all, I appreciate your continued interest in helping me with the problem.  I am using jython2.7.0.  I’ve tried the program on two versions of the Mac OS, El Capitan and an older version on another computer (I don’t recall the number off hand).   

I’ve been swamped with work the last couple of days, so I haven’t had a chance to try your suggestions, but I will soon.  I will post my result on the mailing list.  Meanwhile, I continue to welcome any new insights on the problem.

Cordially,
Rafael
