Aha.
I'm using 2.1.10 (because I didn't like how v. 3.0 loaded large documents).
So we can put it down to that, I'll suppose.
But I'm curious what you mean by "That command". Does v3.0.3 have a "Sort By Date" in the Edit menu?
Or do you mean it has a "Sort Table" in the Edit menu?
But even so, now I realise I don't know how you're using your "Sort By Date US" macro; are you also using a command that's in the Edit menu? And if so, at what point?
