Subject: Re: Problem with popen on windows

Hmm, this has no effect on the backqoutes thingie. It has an effect on
popen but whatever I put in COMSPEC it just stops working. 

C:\WINNT\system32\cmd.exe is the standard, i tried:

C:\WINNT\system32\command.com
C:\WINNT\system32\cmd.exe /MIN
and empty

all have the same effect: no window poping up (fine) but no process is
executed also (not so fine)

why is cmd.exe started anyway?

cheers

Simon
