I, too, have Term::ReadLine-1.03, which pretty much rules it out.

I'm pretty much convinced that it is Term::ReadLine, or at least Term::ReadKey, specifically, ReadKey.xs.

And I don't see where any registry key could be influencing this. (Which doesn't mean it ain't so, just that I can't find any place where it could be!)

If you have Devel::Trace handy, could you try running perldl with it enabled? 

perl -d:Trace \path\to\perldl.pl

[download]

And see where it comes to rest awaiting input?

On my system it is at >> [0] (eval 9)[C:/Perl64/lib/Term/ReadKey.pm:522]:    6: ??? (your output may look a little different as I tweaked my Trace.pm).

The press one of the arrow keys see what if any trace you get?
