Problems with netscape 6 from someone who knows little

[Stephen CS Howe]

I have the following questions about the use of Netscape 6 (or mozilla) under linux Redhat .
I am using Redhat 6.1 because it works for me and I can't see much improvement in Redhat 6.2.).My kernel is 2.2.2-12.

1.Where can I download the latest stable version of mozilla to maybe get rid of some of the bugs that came out with Netscape 6 ? Preferrably in rpm format ??
2.What should I be downloading?
3.How do i integrate what i download with what i have from netscape in the old version?
4.When I start netscape, I have to be online, because otherwise the program crashes on startup with the following error:-
moz_debugger=
***************server Error********************
gethostbyname() failed, errno = 11
## An unexpected exception has been detected in the native code outside the VM.#Program counter=0x48d0e523
#
#Problematic thread: prio=1 tid=0x8054888 nid=0x379 runnable

I think what is happening is that the program is trying to connect to some page or other on the netscape server that does not exist anymore where my installation would have been registered. This is great , but how do I disable it so as I can start up netscape mozilla or whatever offline ?
5.When I am attaching files to my e-mail, can i click and drag from inside my desktop gnome file manager into the message pane to attach the message? I can't get it to work. I have to attach the files manually, one by one. So if I have to attach 20 items, the whole process gets extremely slow, because when you click on the attachments space in the message window, you bring up a file manager window in your home/user directory, so for every attachment, you have to go down the directory path to select the file you want, which gets very time consuming and annoying after a while.
6.Is there any way to send mailing lists via mozilla/netscape 6 without letting the people receiving the lists see the list of names ? I need to do this for my application of netscape and i am getting sick of sending the same message one by one to 200 different recipients . If no solution exists, I will write a program personally to modify the message I am sending manually to allow me to do this because it is a text file that i have tio modify so should not pose problems to my (zero) linux programming experience as otherwise I am going to go crazy. If someone has already written something to do this, let me know and i will buy it off you or pay you to develop it free source if necessary.
