Calling my ISP tech and find out from his end if he can do anything. If not I am going to abort the installation of Thunderbird and stay with OE6.
At this point , it seems to be an issue fof enabling another account or something.He is really good at trouble shooting small and annoying problems really quick.
I don't run out and buy a new OS everytime I have a small glitz in my current OS.
I try to isolate the problem , then analyse a solution , then implement the solution and if I cannot solve a particular problem I reply with knowledgable people who have the expertise to eliminate the glitz....
You see the key is finding the right people to fix your problem....
