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

[Romy Schneider]

Hello,

I have written a Tcl/Tk application with VTK and in it I use three  
separate vtkTkRenderWidgets.  This works fine on my Intel Mac 10.4.8,  
but I can't seem to get all three to display on my Windows XP  
machine, only 2 will actually render at any time.  Packing or not  
packing in Tk does not seem to make a difference, only taking away  
one of the vtkTkRenderWidget declarations actually makes a  
difference.  I declare them all similar to this:

set vtkw [vtkTkRenderWidget .ren -width 800 -height 600 -rw renWin]

with different values for ".ren" (always just below top level) and  
"renWin" .  I did a few searches and the only similar issue I could  
find was here:

Although I'm only trying to create 3 render windows, not 16 so surely  
it's not an OpenGL driver issue?  Has anyone experienced a problem  
like this before or have any useful information on how to go about  
solving it?  Any help greatly appreciated!

Thank you,
Romy
