Hi,

I think I recall I observed the requested behavior (i.e. get hand back
in interractive window or script after a show()) in previous version of
matplotlib.
I remember this cause reproducing this non-blocking behavior of show()
has proven to be a little bit hard to reproduce when developing FltkAgg
backend (I have done it using thread, and it works, so a solution would
be to use this backend when it is integrated).
But with TkAgg and GTKAgg, cvs version, on linux, it does not work
anymore (i.e. show() do not return hand, as mentioned)
I tested some earlier version (0.54 on windows, TkAgg) to see if I have
so false souvenir, but it indeed work as Mark want (i.e. show() is
non-blocking )...So I guess something has changed in the show()
mechanism since, maybe to deal with the new event mechanism?

Best regards,

Greg.
