I cannot select mailto protocol in default parameters for google chrome, as it is marked as unknown application.
EDIT : To clarify, I tried this solution but when I save, and I go back in Google Chrome associations, MAILTO is automatically deactivated.
I cannot either associate google chrome for mailto in the type association, as it is not defined.
When I stumble upon a link in an application or on the web, I get the window for selecting the program, with for only choice the Windows Store.
How can I set this right, so I can open any mailto whether they're on applications or the web ?
