Has anyone created an application with more than 
one wxVTKRenderWindowInteractor or vtkRenderWindow using wxPython before? 

I'm new to both wxPython and VTK and I'd like to 
create a two windowed application. I've tried placing two wxVTKRWI's in a 
wx.Panel - using sizers, I've tried using a wxSplitterWindow - using two panels, 
I've tried creating a new frame with a second wxVTKRWI in it. The strange thing 
is they all work until the application is closed when some error messages are 
thrown up in the vtkOutputWindow...

Are there any special techniques/points to consider 
when implementing two vtk windows?

The errors are:

ERROR: In 
\enthon\src\Vtk-5.0\Rendering\vtkWin32OpenGLRenderWindow.cxx, line 
238vtkWin32OpenGLRenderWindow (04302B88): wglMakeCurrent failed in 
MakeCurrent(), error: The handle is invalid.

Can someone please help! I'm not sure what this 
means... There is no such path.

I'm using Python Enthought Edition Python 2.4.3 for 
Windows.

Kind regards,

Richard.
