I don't have a "c:\program files" directory on my system,
since it's a Swedish version of Windows. I've tested with
"c:\program\internet explorer\iexplore.exe" instead, but
cannot reproduce the problem: Not with subprocess with 2.4
or 2.3, and not with os.popen3 either. For example, I've tried:

w, r, x = os.popen3('"c:\\program\\internet
explorer\iexplore.exe" www.abc.se')

Please test and see if you can reproduce the problem with
Internet Explorer. 

As far as I know, it should be safe to install 2.4b1 without
trashing the 2.3 installation.
