--- Comment #2 from Kevin Meyer billy65bob@gmail.com 2012-03-18 02:36:48 CDT --- IT appears the issue existed under older variations of windows as well, and this was corrected in revision 5089 and 5090. http://code.google.com/p/pcsx2/source/detail?r=5089
But considering the issue didn't show itself on Windows 7 (and Vista by the sounds of it) during these "faulty revisions", I'd prefer to keep it open for now until someone with more experience has had a look at it.
