1) I have setting Show messages in Message Window, but as you can see there is some problem with inappropriate font changes:
This small font in message window is built in and I cannot change it.
2) In the last few versions I am unable to change language to anything but Czech. When I change language to English for example, after restarting jv16 appear in Czech language again. If I want persistent English I must delete all language files but English.lng. So I cannot use other languages, only temporary - to the next restart of application.
