Comment (by ewcgrass):

 Thanks Michael, an openGL issue was the cause. I tried a few other
 applications that require openGL and found that that the problem appears
 to be related to nvidia graphic card drivers after applying recent Fedora
 upgrades (within the last week, but I unfortunately did not keep track on

 I suggest the following caveat for Fedora 10 users who run nvidia video
 card drivers. It appears that a recent Fedora upgrade breaks nvidia
 drivers for at least two legacy cards (GeForce4, GeForceFX5xxx are the
 ones that I've tested). Applications needing 3D acceleration either don't
 work, or cause X to restart! Results for applications that need 3D without
 acceleration vary; NVIZ will not run, but IBM's openDX does. A temporary
 fix is to remove (rename) the xorg.conf file in /etc/X11 to allow X to
 revert to using the default (non-accelerated) video driver (nv in my case
 I presume). Now NVIZ runs fine (including redraw rate for lower half of
 GIS-manager), but my son will be disappointed to learn that google-earth
 and tux racer no longer do. Lets hope Fedora fixes this soon so I can keep
 my sanity as a parent!

 Thanks again Michael. In light of your greater experience on these
 matters, I will let you decide whether this issue should be closed as
 resolved and how so. In the mean time, I will post this issue on the
 nvidia forum and I will test with nvidia drivers from time to time
 following future upgrades to see if Fedora fixes this, and report back (do
 so here?) if/when they do.
