[vtkusers] Multiple Viewports Bug

[David E. Jones]

We use an application with muliple viewports that I wrote.  This program

won't work on an HP Windows 2000 system but it has run on every other
system.

In addition, the splines.tcl example which is in graphics/examplesTcl
doesn't work.  The only curve that is drawn when we run splines.tcl is
the one in the lower right viewport.

Also, I've included a very simple program which I wrote which doesn't
work.
It's called rects.tcl and it's supposed to draw a red viewport on the
left
and a blue viewport on the right.  Instead it draws nothing on the left
(i.e. a black background) and a red viewport on the right.

We are using vtk 3.2:

     vtk version 3.2.0, vtk source $Revision: 1.717 $,
     $Date: 2000/12/13 16:56:19 $ (GMT)3.2:

The computer is an HP PC (Vectra) Intel Pentium 4 CPU 130,544 KB RAM
with Microsoft Windows 2000 5.00.2195 Service Pack 1. The graphics
on PCI bus 1 is by Matrox Millennium G450 Dual Head - English with
the driver g400m.sys.

Have anyone else had a similar problem ?   Is there someone with a
computer like the one described above who could try running
splines.tcl and/or rects.tcl

Thanks in advance,
Dave
