Thanks for the helpful reply. Yes, that’s exactly the reason and, of course you’re right, it doesn’t matter what order the columns are in in AL. My issue was more the fact that this is not how I understand DeviceSorting.txt is supposed to work and I don’t really like behaviour that I don’t understand.
As to your suggestion of unplugging everything, I guess I’m a bit reluctant to go down that road on the principle of ‘if it ain’t actually broke….’.
I just wondered if anyone knew why AL affected DeviceSorting.txt in this fashion, but it’s no big deal.
Thanks,
Andy
