I was trying

In [50]: ts = numarray.transpose(s)

In [51]: numarray.take(ts,(1,2),axis=0)
...
ValueError: Invalid destination array: partial indices require
contiguous non-byteswapped destination

In [52]: tscopy = numarray.transpose(s).copy()

In [53]: numarray.take(tscopy,(1,2),axis=0)
Out[53]:
CharArray([['b', 'e', 'h'],
           ['c', 'f', 'i']])

Is this the same or a related bug? Thanks for the reply and info.
