Problem with a display

[Doll, Margaret Ann]

We have a Dell GX 280 to which we attached a Dell flat screen.  I believe
the flat screen is an E2210.
The Dell is running one of the latest versions of Fedora 12,
2.6.32.11-99.fc12.i686.PAE.

I installed the latest version of Tecplot 360 on the system.  We are getting
errors with this version of tecplot that we also experienced with an older
version of the tecplot.

When we plot a solid, surface graph, then go to "contour ...", if we click
on the ">>" arrows, our session dies.

The /var/log/messages record:

This doesn't happen on other unix systems of ours.  I gather there is
problem with the interface to the display that we are using.  Any ideas how
to fix the problem?
