RE: G2 Problem
It's pretty hard to get older software to run on newer systems. I've got a stack of boxes beside the desk (and the stack is taller than the desk) of software that won't run worth using, if at all, on my newest pc's. It's how the software industry keeps themselves employed. It also works that same way in the business world. I made a career of developing applications and upgrading them. There was only slightly more backward compatibility in business systems.
However........
XT offers you the possibility to run older applications in "older pc" modes. You might look into running G2 that way. I don't remember how to do it, but I'm sure someone will fill that in for us.
