I'm running Thunderbird 24.3 on Debian 7 and sometimes when I click on 'Write' and it opens up a new window it's not in focus and my keystrokes are sent to the main Thunderbird screen not the new Write screen. The Windows Manager I'm using is XFCE4.
It's happening for other users of the same system and I have yet to find a pattern to reproduce this.
I've also had this happen with firefox 27.0.0 and with Thunderbird whilst using thunderbird inline conversations plugin on one of the machines which doesn't start a new window.
What I've tried and I still have the problem
- clicking on title bar
- Check error console
- Start a fresh profile (Move the .thunderbird directory and start completely fresh)
Update
Tried the thunderbird 24.4.0 and still have the problem.
Noticed that if I quickly hit Ctrl+n about 10 times I can re-enact the problem.
