1. Take for example French LNG file and remove the lines 6150..6153 from it (don't forget to backup the file!).
2. Open TC Configuration dialog when some non-English and non-French language is used (German for example).
3. Go to the Icons page (Symbole (Icons) in German): all the controls are in German.
4. Without closing the dialog, go to the Language page. Select French (Français), press Apply.
5. Again, without closing the dialog go to the Icons page (Icônes in French): all the controls are in French, except for the Icons in main menu group which remained in German (Symbole in Hauptmenü).
Expected: the Icons in main menu group should revert to the default English, as there are no lines in the LNG file.
After close/reopen the Configuration dialog those controls are English, as they should be (that's why I wrote, it is a small bug).
PS(OT): Clo, I hope you're not offenced with my barbaric experiments over your language file.
