the text editor offers me to open a file when I click on the Preview button mode translated page (language America to french via google translate).
I'm using google chrome v21.0.1180.83 m
to reproduce the bug:
to a language other than the original one, ask google to translate .. click yes then click on the message preview
you will see a window opens to browse on computer
in my opinion this is the button download a file that starts because of the translated page (buttons are distorted).
