Yes, I've had this problem since updating to Perl 5.8.0. I always have to double enter when using CPAN now.

I think that at one time I went back and tried Perl 5.6.1 again, and the problem went away.

And that is as far as I got in my troubleshooting. On my main Linux machine, it works fine. Only on Cygwin is it a problem, so I don't use that machine very often

Also, I just grabbed your script and tried it under Cygwin, and the modes 1, 2, 3, & 4 all acted exactly the same. Mode 5 was flakey to say the least. Especially wierd, mode 2, which isn't supposed to echo, but does.
