[vtkusers] deleting actor from renderer

[Abeer Mahdi]

hello,

I have tryed RemoveActor (vtkProp *p) from vtkRenderer, and after that I 
call renderer.render();
However when running the program and changing the parameters of the graph, I 
get a popup message saying "SetPixelFormat failed" Do you know what is 
causing this ?
Thanks in advance

Abeer
