About once a day when I go to gmail's website using Desktop Chrome, Windows 8 asks which app I want to use to send email. I select gmail, my current/always default, and it shuts up briefly. However the next day or so the message always comes back. There's no checkbox for "always use this method" or anything and I haven't changed the app to use for mailing or even used any other mailing app.
How can I get it to use gmail and only gmail and stop asking me?
