I found that my "security violation" went away when I downloaded Netscape 4.51 and installed it in place of my 4.01.
That is to say, I had committed the technological faux paux of having less that current technology, rather than having a server with an inpenetrable firewall, though, typically, the failure notice failed to distinguish between problems.
If I plan to write computer commands, I'll need classes in advanced ambiguity and vagueness, tho perhaps just writing them in a foreign language would suffice.
There's some words for you.
Blessings,
Barbara
