Here's the java alternative:
>From java.lang import Runtime
R =3D Runtime.getRuntime()
R.exec('"C:/Program Files/Mozilla Firefox/firefox.exe" www.jython.org')=20
Works. But os.system still seems buggy.

Gareth,
You're correct - looks like we're hitting a bug here?
Still you could use the java class System to get better results (TM).
