I'm using wxVTKRenderWindowInteractor 1.36 (WinXP, VC++2005)

  Date:      $Date: 2008/04/14 15:12:00 $
  Version:   $Revision: 1.36 $


with wx v.2.8.7.  I have a single wxVTK window in a wxAUI docking 
frame layout.  I too found that OnChar() was not getting passed 
through to the wxVTKRWI, but that OnKeyDown() was working fine. 

A quick fix for me was to handle the char event in OnKeyDown().
I invoke a CharEvent after the KeyPressEvent (near line 485):

  InvokeEvent(vtkCommand::KeyPressEvent, NULL);
  InvokeEvent(vtkCommand::CharEvent, NULL);   // <--- added


This fixes the problem for my current case. 

Also noticed an issue with small offset to the vertical "y" pick 
position.  When I get a moment I'll try to track that down.

Nigel
