Solution: With the focus on the open compose window, select from menu: Tools > Mail & Newsgroups [Ctrl+1]
There are related inconsistencies though. * If an email is opened for reading in a new window, the shortcut key changes: Tools > Mail & Newsgroups [Alt+1] * If only search, message filters, activity manager and preferences windows are open, no top level menus are visible and neither [Ctrl+1] nor [Alt+1] does anything. The latter is a bug. However, there is a work-round that works in the other cases as well: * Launcher > right click Thunderbird icon > "Compose New Message", which then gives access to the first solution above. This problem is irritating for me, because I often have large numbers of Thunderbird windows open, and until I found the above solutions/workrounds, if I accidentally closed the main window (which I have done many times), in order to reopen it, I had to close all the other windows, thus losing track of all my work-in-progress when I restarted Thunderbird. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1507652 Title: thunderbird main window can't be started from unity starter icon if email compose window is opened To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/thunderbird/+bug/1507652/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
