I have some questions about your software and before I ask I must greet you, its a WONDERFUL program!

So...I liked more the QML GUI but when I try to open some menus the app just doesnt open them, why so? These menus are 'Search' , 'Routes', 'POI', 'Map->Download', 'Mode->*any*', 'Options->*any*'. Basically I cant search, cant change routing options and blah blah..that problem doesn't exist in the GTK GUI.

And the second one, for example - I have downloaded a map tile of a particular area on 15.03 and that area gets updated on 18.03 will the program check in any way that there is a new version or I have to delete that tile and download it again?
Thanks in advance!
