Thanks Omar. Then it must be a bug that I cannot edit fields in the Contact window. In fact there are a number of bugs with it, I'll report them individually. Or is there already a list of known bugs?
This is not the issue of upgrade SERP. But serverip.dat in this case contains the value: 192.168.88.12:1301, so this is local IP of the server with SERP.
Anyway I don't understand what do you me...
