Pylab window won't close


I run python + pylab in Linux.

When I type:

import pylab


A window pops up but nothing is drawn
in it (!?!). So I type:


The plot is then correctly drawn ( but
I still do not see the lower buttons of the toolbar !?!)

My problem is that I cannot close the
plot window nor by clicking the “upper-right-cross” button of
that wndow, nor by typing:


The window remains displayed…

Does anyone have an idea where this
behavior comes from ? I would really like to be able to close my plot windows.

I have following lines in matplotlibrc:

backend : GTKAgg

interactive : True

toolbar : toolbar2

Thanks in advance for your support,
