Just installed OPUS client on my second PC. Networked and linked with the server (green boxes on both screens).
Problem I have is that whenever I enter my destination ICAO code on the server, the box remains yellow (no matter what destination I put in) and as soon as I click on 'update weather' the contents are removed and the cursor placed back there.
It would appear that it does not know where to look for airport information. What have I missed?
