Emacs stuck when error occurs in ange ftp

[brianjiang]

I often met the problem that when I use ange-ftp to edit the remote
file,  if something wrong happen in the ftp connection (e.g., enter a
wrong password, or other unknow ftp error),  the emacs then stuck. C-g
can not break it and I have to use Task Manager (WIN XP) to kill the
emacs process!

Have you also ever met the same problem? How to solve it? Thanks!

Brian
