my PB has been running slow for a couple of hours, so i decided to have a look at 'top', and saw that there was a process that was called 'TruBlueEnv' taking up about 70-80% of the CPU. then i had a look at Activity Monitor and viewed all processes, hierarchieally and there was a process with the same PID, but it was called '(null)' and it was under 'WindowServer'. well i thought that was a bit weird, so i just killed the process, now my CPU use is back down to about 30-40% from 100% before. i was just wondering what that process was? anyone know what it does, or why it was behaving like that?
