Hi akvisto and welcome to the PCLOS Forum.
I had a similar problem in December when I upgraded from Thunderbird 2.0 to 3.0
Log in as root into your file manager (I use Krusader) and look in your "/home/user" directory for the ".thunderbird" directory. When you find it, rename it to something else (eg. .thunderbird2).
Install Thunderbird 3 from the PCLOS repository of your choice and it should work now. However you will find it sets up a clean new .thunderbird directory with none of your previous saved messages......
Hi caerhays, thanks and thanks for prompt response.
I followed the steps you proposed without success,
- also tried to force earlier version of Thunderbird (which worked fine before) but the menu item in Synaptic is ghosted,
- also installed Evolution with the same result as before - nothing happens.
So Thunderbird, Claws, Seamonkey and now Evolution have all been tried and all refuse to work.
It seems that anything with a mail component to it will not run on my system.
I wonder if I have inadvertently removed a dependency, or something else, that kicks these off.
Best wishes
