Welcome to 2019?

I'm still using X6 with no service packs because of the Eula change.. My wife has been trialing 2019 because she found X6 impossible to use on Windows 10 with a 4k monitor.. The menus are white on white and everything is tiny. If anyone know a solution to these problems we would be very glad to hear it. Meanwhile, how to disable the welcome screen on Coreldraw 2019? I presume it insists on periodically connecting to the internet to keep the program activated. How long can it be kept offline before this happens? And I'm still confused about "upgrade protection". What exactly is it? Thanks
