So can you run the module tests?
>>> scipy.integrate.test()
>>> scipy.optimize.test()
etc. Then maybe you can find out where those windows are coming from.

regarded that as 'Numpy 1.4'. So I see 1.4.1 as a bug-fix release for 1.4.0,
not the place to remove something. Updating the docstring like David H.
suggested makes more sense to me.

That said, I don't feel strongly about it either way.

Agreed, no warnings should be triggered.

Thanks. Most of the credit has to go to David though for the good build
infrastructure and helping me figure things out!

The binaries for python 2.5 should still follow by the way. That requires me
to duplicate my 2.6 build environment and may take a little bit of time.
