Works for me.  What version of Windows are you using?

Windows XP Pro.

I installed Jython in 'C:\Program Files\Jython2.5a1+', i.e. the directory
path contains spaces !
I suppose Windows Explorer set quotes around filename in %0 if directory
path contain spaces,
so if you use "%0", the quotes are doubled and you need to first remove the
eventual quotes of %0,
i.e. do "%~0".

Thanks; I was using c:\temp to test which explains why I wasn't seeing the 
problem.

I fixed the installer in r4972 to use our new launcher scripts, which handle 
spaces in pathnames.  2.5a2 should do a better job for you when it's 
released.
