Absolutely no issues whatsoever. I work on this project, and have thoroughly tested Poser 4, Truespace, 3DS Max, and Photoshop on this platform. I have had several builds of win2k on my work system for the last several months, and have no problems. Win2k is so stable, you won't believe it. I would suggest build 2190 or above, so RC3 or above. Hope this helps, co(V)(V)union
