Bill: Thank you for all of the above information. I googled for the
CPU and stepping number and looking quickly at the results, I don't
think it is a problematic CPU. Will look into the other things you
suggested. I'm curious as to why the latest Google Earth for Linux
won't run on it, but, as you pointed out, it could easily be that the
Application software is flawed and if that is the cause, it won't fly.
We have one Google Application that comes with a small version of
WINE, to run on Linux, but I think that is Google Picasa and not
Google Earth.   Lanny
