Whichever way... I am using a MS keyboard having a dozen "multimedia" keys, incl. a "mail" key (with the sketch of an envelope on its cap) which is supposed to call or activate the default mail app on Windows. Here however, pressing the "mail" key opens Microsoft's stoopid "mail" applet that isn't even capable to access my main POP/SMTP account (yet I tried, hard !).
I have asked Thunderbird to please be the default mail application, but it's had no effect on the "mail" key binding
