It turns out that the problem described below happens with so-called CVS emacs. With

GNU Emacs 21.3.1 (i386-msvc-nt5.1.2600) of 2003-03-28 on buffy

this problem does not exist. So long with CVS emacs...

Hello all,

I am using in my _emacs file:

;; Setup Emacs to run commandproxy as its primary shell.
(setq shell-file-name "cmdproxy")
(setq explicit-shell-file-name shell-file-name)
(setenv "SHELL" explicit-shell-file-name)
(setq explicit-sh-args nil)

and M-x shell RET starts a shell successfully. However, when I run an executable that last quite a while and if I decide to send a <break> signal using C-c C-c or the menus, emacs becomes nonresponsive, and if I locate the executable file and end it using Windows Task Manager, emacs becomes responsive again, as if nothing has happened. If I kill the buffer, no problem again. But if I send any other signal, it hangs and does not recover.

M-x version RET reports

GNU Emacs (i386-mingw-nt5.1.2600) of 2003-12-28 on SERVER

What do you think could be the problem?

Thanks a lot,
