(replying to both Samuel and Tim) ok. I thank everyone who tried to help. Once Thunderbird 52.7 (or later) is added to the Fedora repository, and I've verified the fix to a separate Thunderbird issue, I'll try to communicate with Thunderbird people about this issue. If they suggest submitting a bug, I'll do so, and post something here with the bug number. _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx
