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
