On 6.1 here and `cmd-n` and `cmd-o` definitely do not work immediately after launch.
I especially agree with the comment by Gareth Lind; I think the problem is that although Adobe has its roots on the Mac, their programmers these days are primarily PC-oriented and don’t care much about the Mac any more, which is evident from the poor support for some key Mac features as well as sloppy errors like this.
