Re: [Lynx-dev] Issues with -dont_wrap_pre and -nomargins

[Stefan Caunter]

The shell environment will obey .lynxrc, created by [O]ptions, so have
you tried
Show images - ignore
Verbose images - OFF

There are also parameters that will appear if you edit lynx.cfg to
make them appear in Options page.
