Add " /connect" at the end of the file name in the target box of the link you use to start ANRB.
i.e. before "C:\AirNav RadarBox 2009 - 3.01 Beta\ANRB.exe"
after "C:\AirNav RadarBox 2009 - 3.01 Beta\ANRB.exe" /connect
NB: Don't amend the details of the text in speech marks, just add /connect at the end
