After my laptop crashed and I restarted the laptop. Everything works normaly, except the Tunderbird, wich after a long wait gives me the message that thunderbird has crashed and sends a crashreport. My conclusion is that with the laptop crash something was damaged. I could reinstall Thunderbird hoping that will solve the problem. However before I want to backup the mailfiles. These are substantial and have a lot of emails in many folders and over many years. It would be a disaster if I lost them. I cleaned up a lot in webmail. Wat should I do? Crashreport.
