An unusual problem happened when I upgraded from earlier version of thunderbird - which was working fine - version 9. I decided to update. So update to latest version. Once I did this something happened: 1. When I go to address book, I select address book and then select Export. 2. The export window pops up, but the field where you select FILE TYPE is blank - there is no CSV, TXT etc. options to select. So... I saved a copy of my profile as a back up. Then I uninstalled that version. Then installed the version my husband is using - 24.5 - which he uses with no problems at all. After installing the 24.5 version I still have the same problem. We are completely stumped and don't know what is causing this. Something must have happened when I upgraded from the very early version 9 to the 31. Its like its not seeing the FILE TYPE to display when I go to export. Any suggestions or help would be greatly appreciated! Thank You Daphna
