probably related to bug 1287846. You don't mention whether you tested in safe mode or new profile.
I have not tested in safe mode or with a new profile. The problem is intermittent and it does not happen every time, only sometimes. It has been happening for at least a couple years thru many version of Thunderbird.
These types of issues (this and bug 1287846) tend to be hardware or other factors. If you aren't able to test safe mode please should at least list your addons. And a more specific characterization of average frequency. For example does intermittent mean once a week? Once a month? In clumps?
Component: Untriaged → Message Compose Window
Summary: Clicking WRITE will open two compse windows → Clicking WRITE will open two compose windows. intermittent
Intermittent means several times a day. About 1 in 5 five times I will get the two compose windows open. Plugins activated: none Extension Add-Ons: 2 - Lightning - Show Address Only ( https://addons.mozilla.org/en-US/thunderbird/addon/show-address-only )
I've never seen this on Windows.
I have tried safe mode only a few times, but have not seen the issue occure in safe mode yet.
I'm not sure what to expect, but try with Show Address Only disabled and thunderbird *not* started in safe mode. what are your results?
I created a new profile and copied over the files below and the problem still occurs for me in new profile. Mail directory ImapMail directory Prefs.js (need to search/replace old profile name with new profile name) abook.mab Address book history.mab Address book cookies.sqlite Lightning permissions.sqlite Lightning calendar-data/local.sqlite Lightning key3.db Passwords logins.json Passwords cert8.db Passwords chrome/userChrome.css Custom CSS settings I then re-installed the Show Address Only extension and problem still exists. I just read Wayne's suggestion from september, so I will now disable the Show Address Only extension for a week and see what happens and report back.
So running with Show Address disabled and not in safe mode for a week, the same issue is still happening.
Does it happen with beta from http://www.mozilla.org/thunderbird/channel/ ? When using keyboard cmd+N ?
