Well, I know what I did to fix my problem, but yet I *don't* know what I did to fix my problem.

Just today I remembered the first time I tried to log on to Yahoo and retrieve HTML files. I remembered trying to install WWW::Mechanize - I think - and getting an error message at some point telling me that I needed Crypt::SSLeay.

So today I got on to CPAN and installed Crypt::SSLeay and re-ran my script, and it works now.

So I now have one more question, and one more comment.

My comment is that I still don't know why $mech->field() had to be replaced with $mech->set_visible() when running on the Linux box.

My question is, will someone explain to me why I needed Crypt::SSleay in order to get my script to work?

Thanks to everyone for their comments and assistance.
