I did some testing on this a couple of years back, and it's basically a memory glitch Some XP machines will run XyWin. Others will load the naked .exe file, but if you configure it, they choke. How much RAM, what kind, and the like vary. If I ever get a spare minute--a spare millisecond--I will try and find my results.
