[PD] pd~ subprocess on Windows

[Jean-Yves Gratius]

Hello,
With pd 0.47-1, on Windows platform (8.1), installed in a standard 
'program files (x86)' path, I'm trying to launch pd~ subprocess. (pd~ 
version 0.3)
In the help patch pd~-help.pd, whener I click on the message [pd~ start 
pd-subprocess.pd(, the console starts, the new pd windows appears, but 
the patch pd~-subprocess.pd is not opened.
I get the following error messages :
> Files: can't open
> (x86)/pd-0.47-1/bin/pd.com: can't open
> -schedlib: can't open
> C:/Program: can't open
> (x86)/pd-0.47-1/extra/pd~/pdsched: can't open
> -path: can't open
> (x86)/pd-0.47-1/extra/pd~: can't open
> -inchannels: can't open
> 2: can't open
> -outchannels: can't open
> -r: can't open
> 44100.000000: can't open
> pd~-subprocess.pd: can't open

If I move pd installation folder to a path without spaces, it works fine.

So, in order to use pd~, I have to install pd in a path without spaces 
(not as in 'program files (x86)').
Is this a known bug/limitation?

Thanks
