Expect script works in 1.5 but fails in 1.7

[Bogdan Nicolau <b_nicolau at yahoo dot ca>]

? 
Hi,

I have a simple Expect script that starts as:

set timeout -1
spawn ftp a.b.c.d
match_max 100000
expect? "*Name (a.b.c.d): "
send -- "anonymous\r"
expect? "*Password:"
send -- "anonymous\r"

This is fine in Cygwin 1.5 on my PC (installed in Nov 2008)?yet on some other PCs where I installed, last week, Cygwin 1.7 it fails at the Password introduction. I tried more combinations of stty echo and/or raw but without success.
Either it hangs without prompting the "Password:" or it prompts and gets the first character but the rest of chars are echoed on a new line and the login fails.

Thank you very much!
Bogdan Nicolau

A short sample of my setup-for working PC- is here:

[~]$ cd "C:\backup\LaptopTools\ExpectWinUnix\expect-5.44.1\example"
[/cygdrive/c/backup/LaptopTools/ExpectWinUnix/expect-5.44.1/example]$ strace ftp a.b.c.d
