The disappearing menu just happened to me again. I clicked on the menu to select "Tools", then moving the mouse makes the menu disappear so that nothing is selectable. However, moving the selection by using the keyboard DID work without disappearing the menu.
I just switched to Firefox to add this comment in the bug report, now going back to Thunderbird to verify my description I find that the menu is working OK. Thunderbird was not restarted. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/999020 Title: thunderbird 12.0.1 menu's not usable on lucid 10.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/thunderbird/+bug/999020/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
