Eh, I'm completely ignorant when it comes to windows batch file creation,
what I put toghether so far is based on "monkey see/monkey do"
and some internet searches.
But I guess we'll have to either be happy with it (plus your changes above)
or not do anything at all, since
it seems no windows based developer can be compelled to help on this one
(and the RC release is Monday)...
Cheers
Andrea
