[ESS] Jags C-c C-c opens an external terminal window under Windows

[Vitalie S.]

Dear ESS community,

I have just started using ESS Jags Each time I run .jmd file through C-c
C-c a new cmd window pops up.
Can I somehow change this behavior?

also commands like
system rm -f seeds.ind
system ln -s seedsindex.txt seeds.ind

give the error messages:
'rm' is not recognized as an internal or external command,
operable program or batch file.
'ln' is not recognized as an internal or external command,
operable program or batch file.

OS is Windows Xp, ESS 5.5 and emacs 23.1

Thanks a ton.
Vitalie.
