Hi Ryker, Thanks for taking the time to respond to my question. The G5 is a Power PC based computer.
I was just inspecting the 'Get Info' information on the Viewer 2.0 app (which clearly shows that it is, in fact, an Intel only application) when your, and Tiger's, response arrived, almost simultaneously. I suppose I'll just have to resign myself to the fact that I'm using antiquated technology. I certainly don't have the $'s, L or US, for a new machine.
