New spherebench problem ( was RE: [vtkusers] Sphere Benchmark runs, but renders black window half way through

[John Shalf]

Hi,
I get the same behavior on my SGI Irix system with SphereBench (actually both behaviors... the
disappearing sphere and the jittering sphere).  I believe it has to do with the version of TCL/TK that I
am using more than anything else.  It didn't do this until more recently.

Not really much to worry about I think.  Probably something wierd with the tkrender widget.
