Thanks, for fixing everything so quickly - I'll test it tomorrow.
BTW: are you intentionally sending the last few messages ONLY to me and
NOT to the mailing list !? I actually think the mailing should be
configured that a "normal reply" automatically defaults to go only (!)
to the list.
(I'm on some other lists that know how to do that).
Who would be able to change that for the numpy and the scipy list !?
