Putting a running job into the background with cygwin zsh?

Putting a running job into the background with cygwin zsh?

I'm using the cygwin version of zsh 4.2.0 on WinXP.

If I run a Windows program and later want to put it into the background,
Ctrl-Z has no effect.
`stty -a' indicates that the suspend character is ^Z.  Does this work for
others or is it a known limitation in the cygwin version?

Interestingly, the old Windows native zsh port (by AmolD) would always
return immediately when invoking "windowed" Windows apps, i.e., if I typed
`notepad', the shell would exec notepad.exe and immediately provide a new
prompt. It only did this for apps designed to run "windowed", so would work
for "notepad", "write", etc, but not for "java" (I used "javaw", which is
"windowed").

Thanks,

    --- John

Since windows does not have job control nor pseudo-terminals, I
suspect that the backgrounding behavior is part of the Cygwin runtime.
Windows programs are not linked to the Cygwin runtime.

That's depends on which Windows runtime you link with.
