[matplotlib-devel] Mouse event blocked in 1.0 but works with 0.93 ?

Hello,

My pyqt4 app use the matplotlib pick event.
Cliking on a point in the graph triggers an event
but with matplotlib 1.0 it does not work anymore
while it was working fine with 0.93.
(Matplotlib version is only what was changed)

Any one who might be aware of a matplotlib change that could have
induce that issue ?
Any idea/help on where I should look for and how to fix this?

Thanks in advance,

David
