I have been working with unity for over a month now, and it is much better than coding the game in C (been there, done that). I have been making a highly detailed realistic simulation, etc. Anyway, more and more frequently, when I am testing the game in the editor windows suddenly comes up and say “unity editor has stopped working and must be shut down” or "unity editor has performed an illeagal operation and must be shut down. This Is frustrating me to no end since it does not save before it terminates. Is there a Unity log file anywhere that I am missing? Has anyone had this problem before? Does anyone now how to fix it (please say yes 
).
I’m on windows 7 unity 2.6 duel core nividia gforce graphics card, 8GB of ram. In unity I am using the Detanator package, Advanced Mouse Look (wiki script), and parts of the default FPS controller. When the crash occurs at max the CPU is at 88% and unity was functioning fine, no lag or anything.
