Just for a "heads-up" guys. Recently installed Thunderbird on mine and friend's laptops with no issues. Been trying to get it working also on my desktop for the last few days and it crashes repeatedly on import. Tried all sorts of tricks like putting the pst file on a USB stick and uninstalling/reinstalling Thunderbirds and Outlook. Finally found earlier problem reports down to specific Thunderbird versions. The laptops have v.37 but the desktop has v.38. An earlier fix was to install v.24 and then upgrade. Just tried this and it worked a treat. v.24 imported all my outlook stuff and then simply upgraded to v.38. Incidentally, all 3 machines are running Windows 7 and Outlook Express. Best Regards, Phil
