[vtkusers] Re: vtkusers digest, Vol 1 #2264 - 3 msgs

[Andres Barrera]

Thank you Clint. I had done what you say, but without setting 
"vtkMapper::GlobalImmediateModeRenderingOn()". I had a very weird behavior 
in both windows (actors changing colors and desapearing). I'll try your 
suggestion.

Thanks again
