Hi Galuf. I'm not sure if PT runs on XP, reason for this being I always have both Windows XP and 98 installed on my pc so I can avoid being in situations where older games don't work. I would suggest doing the same thing. It doesn't take that long and the advantages are considerable. Or, you could use "Run in compatibility mode" but most of the time I found that function completely useless.
As a side note, BG 1 and 2 run fine on Windows XP.
