When i type the RU server adress, i don't have any place to login or do something like that.
In order to use the server in the relay role you do not have to log in/sign in on it. Simply specify your server address in connection properties and use the Internet-ID of the Host in order to connect.
Regarding #1 - Sorry, I think I used the wrong term. I meant two Monitors. It seems to start with dual monitor view, and switch to #1. This takes time on a slow connection, and possibly can be avoided?
Ok, no problem. Actually, your monitor selection should be remembered for this connection so the next time you start it it should immediately show you the selected monitor. Is that the case?
Can you explain the way you currently implement the auto-reconnect (using IP? Using ID?)
Auto-reconnect is just what it is - the program attempts to re-connect to a remote computer if there is brief network interruption, usually a few seconds long or more (i.e. noticeable by human).
and how to make it always check for correct IP by ID and use the correct (modified) IP?
Frankly speaking this is the first time we see that a dynamic IP address is reported as a possible cause for connectivity issues. If network device (e.g. router) and local network in general is configured properly, there shouldn't be any issues with Internet access even if a network device is assigned another IP address.
