Oddly, I saw very similar behavior recently (I didn't see the
attachment...). What I found was that the canvas was still
responsive, but that it "stole" the mouse from any other window (wx
widgets or system widgets) and that this happened on Linux but not
Windows.
I believe that adding
self.ReleaseMouse()
at the end of the event handler will alleviate this problem. It might
be best to do (assuming you bound mouse events with the
Canvas.mpl_connect() ) to do
evt.guiEvent.Skip()
if self.HasCapture(): self.ReleaseMouse()
I haven't fully explored this problem myself, but I am no longer
experiencing it...
