[ESS] ESS on windows and shell()

[Alessandro Piras]

Hi, I'm having some problems with ESS.
> shell('wgnuplot.exe')
Warning messages:
1: In system(cmd, intern = intern, wait = wait | intern,
show.output.on.console = wait,  :
  C:/Program not found
2: In shell("wgnuplot.exe") : 'wgnuplot.exe' could not be run
>
However, that same command works correctly using Rgui. 
Any idea about this?
