I recently loaded Creo 6 (220.127.116.11). In my office, I have my laptop screen extended to my 2nd monitor, Creo will not launch. If I 'project PS screen only' everything works fine. As long as the program is open I can extend to both screens. I do not have this problem with my home setup. I believe the extra monitors are the same make and model, so it seems unlikely that it is graphics card related. I did not have this problem with Creo 4.
