Subject: Corrections to CD-ROM code


I bought your book from the U of M bookstore for use in a class
(CSci 5110). I started building my prototype application using
some code from your chapter 4. In sort, I found some problems.
Some things seem to be bugs, and others infelicities.

I was trying out code on Linux using wish4.2 and Windows using
wish8.0; part of the problem seems to be the code that lets
the programmer not worry about which version of menus to use.

Do you have any corrigenda for your examples in your book?
