do not use ver 3.0, had it, bad news, it added a network to
trusted sites, CANNOT be edited out!! i had a copy of 2.6
so i removed v3 and am very happy using it. v2.6 is available from
Broderbund if you can find a copy on CD

about 90% of the attempts to break in were coming from that
network. v3.0 let them in. would set the program to 'block'
and in 1 minute or less, it was back to 'trusted'.

i made the mistake of going to lunch and when i came back
puter was an absolute disaster area, format/reinstall
was only solution, beware!!!!!!.
