Airnav,
As you are aware I reported the duplicate issue and the freeze of ANRB with network on,in 3.06, now that others have suggested it is because of sorting the list I can confirm this is the case, I always sort the network flights by registration, so I can identify the aircraft that have no info, maybe just something silly we all do ! but i never thought of it before :)
But this would appear to be the problem, as I have run ANRB with local and network flights on from 20:00 yesterday until 16:30 today and not touched anything and all is performing well, to confirm all was OK I unticked the network and all aircraft disapeared which didnt happen before as some aircraft would remain.
I am convinced this is the reason now but it does not explain every case, maybe something to do with all the variables of machine, O/S etc etc.
