[vtkusers] How Can I force Renderer not to render every time I switch windows?

[sandarak at wp.pl]

Hello!

Is there any method to stop VTK Renderer from rendering every time I'm
switching from main program window to window containing renderer?

Im using ITK + VTK + FLTK and VTKFlRenderWindowInteractor class.
It'seems that renderer updates whole pipeline, when I'am switching to window
with Renderer.

Can anyone help me with that?

Regards
