------- Additional Comments From the3dfxdude@gmail.com 2007-28-07 11:31 ------- Since multithreading has been fixed now, this might explain the change of behavior. However you never have identified the problem specifically. So if you take the advice of stefan in bug 3615 comment #33, this can just be explained as a bug that still affects Rainbow Six specifically. Please attach the crash output.
