Timeout in orderSubjects().   

I was running the CodeRuler in Vista on a dual-core laptop using the sample random-peasants code, my ruler stops and the console displays "Timeout in orderSubjects(). Will no longer be called during this match." 80% of the time when running against other samples. I deleted everything in orderSubjects() but the same thing still happens, and it only happens to me(the sample rulers are fine). I've tried all kinds of stuff such as shutting down the anti-virus, upgrading the JVM, running in debug mode etc, but my ruler still stops after an uncertain period of time. When running in debug mode, my ruler simply stops and it gives me a threadDeath exception. At last, I tried to run the program(javaw) using only one core(by setting the affinity), and it worked fine till now. Does anyone know if dual-core is a problem to CodeRuler or is it because of something else which causes my ruler to stop? Also, is there a way to set an application to run with one core only permanently, because it is very annoying to turn off one core every time I test my ruler. Thank you.
