would you have any idea how to solve this ?
No, I have never seen this.
1. What OS are you on?
2. Do you have a small, self-contained script to reproduce the problem.

Hello everybody,
I could finally find a way to solve my problem with right-clicking on a
mayavi scene to use a contextual menu.
As a reminder, my problem was the following. When selecting one item of
the contextual menu, my dialog was frozen and the only way to get the
hand back on it was to right-click another time. To make it work, I
stopped using the add_observer method provided by Mayavi to
mouse/keyboard... interact with the scene and I decided to stay on the
wxPython side using a wx.EVT_CONTEXT_MENU event. It seems to do the job.
For those interested, I join a little script that roughly shows what I
described above.
see you
Eric
