[vtkusers] Limit on # of vtkTkRenderWidgets in Windows XP?

[Romy Schneider]

An update for those who may have similar issues in the future:

I solved my problem by changing the order in which I packed and  
placed Tk widgets in my window.  I'm still not sure why this in  
particular solved the issue, but I was placing a button in the same  
frame as the renderer with the 'place' command.  Moving the  
declaration and placement of this button to after the render window  
widget declaration and packing caused Windows (or Tcl/Tk) to allow my  
third renderer to be seen.
