Not working in email new window Rated 4 out of 5 stars

It seems not working opening an existing message in a new window (but it works in a new message window!).
(Thunderbird 17, CTB 1.1.6)

This review is for a previous version of the add-on (1.1.6). 

You are right, buttons didn't get styled, when an existing message was opened in a new window.

Issue fixed with v1.1.7.
