[vtkusers] RenderWindow question...

[N Smethurst]

Hi Tuhin

I am a total novice when it comes to x-windows programming, but I wanted to
ask if you could expand on the implications of this, specifically could this
have anything to do with the memory leaks that we have been experiencing
when opening and closing muliple render windows?
