So, you say the current Firefox works, but (good old) Vista doesn't want to "talk" about it. I had some problems with a load of a printer driver too, no forgiving on how the PnP was handled, I tried to uninstall and couldn't find it in Programs or in Uninstall...Vista is not ready for prime time. What's one to do when their computer just crashed, even the old stock, clearly not ready for Vista ever, has been updated to vista.

Thanks, my two XP and one W7 are now running Thunderbird 2.0.0.24, that's the latest 2.0 I can find, I think it is the end of the 2.0 line. The links provided were helpful, but for some reason I felt like I was stumbling along in a dark tunnel before I finally clicked on the right link to start a download of 2.0.0.24. Is it just me, or do these "download" sites have a hidden agenda? No too hidden I guess, they are all trying to somehow make some money.

Sue, an e-mail account password cannot be arbitrarily changed with Thunderbird. Thunderbird is not in control of the password, the server controls it. Thunderbird simply sends the password to the server that's already configured there, to signal to the server that "hey, this is legitimately Sue (because she has the correct password) who wants to open her mailbox." If you wish to change an e-mail password (for Gmail, Yahoo, your local ISP, whatever mail service may be involved), the change must first be done at the service provider. Then you enter that new password into Thunderbird when prompted for it. Thunderbird configuration does not provide a direct entry field for the password. Some e-mail programs do, Thunderbird does not. It will prompt for the password when needed. There's a checkbox on the password entry dialog Use Password Manager to remember this password. Enabling that option will make Thunderbird retain the password in its internal settings from that point on and thus not need to ask for it again ... unless the password is changed on the server which causes what Thunderbird has saved to be wrong. If the "remember password" option is not enabled, then Thunderbird won't save it and will prompt for the password each time mail is checked for the first time during a new session. There may be passwords involved for both receiving and sending mail. Usually it's the same password both but in some instance they can be different.

Yep, erased the saved PW2 and tried to send an email, was offered a chance to inter PW1 and the transmission of the email went. Checking Options/security I don't find PW1 saved, I may need to click on "save password" on the next use. Thanks, this comphelp has been helpful as always.
