I have used Thunderbird for some time on an XP computer and have just bought a Windows 7 computer. I used Mozback up to back up all files, settings, email addresses etc from the Thunderbird on the XP machine. I copied the Mozbackup backup file onto the desktop if the windows 7 machine and also into My Documents on the windows 7 machine. I then downloaded Thunderbird (v 3) from the internet onto the windows 7 machine, launched it and tried to import the backed up settings from the Mozbackup file on the desktop. The Windows 7 machine has launched an "Import wizard" and opened a dialogue box stating "Import files from ..... " but the rest of the box is blank and clicking on Next has no effect. How can I get Thunderbird on my new windows 7 machine to recognise the Mozbackup file that's sitting on its desktop? Any advice gratefully received.
