[vtkusers] OffScreen and blank window

[ABE Hiroshi]

Dear Clinton and all,

Thank you for your suggestion, Clinton.

I put the lines in vtkCarbonRenderWindow and saw what happened.
Pop-up problem was still remained. May I understand your fix is for  
remaining window problem?
If so I cannot see the effect of the fix because I haven't any code  
with the problem so far.

Regarding a call, DisposeWindow, I found it is called in  
vtkCarbonRenderWindow::Finalize(void)
So I'm afraid it is not necessary in DestroyWindow.

Regards,
