Application errors in Mac OSX get logged but they rarely take down the entire system unless they're very badly written. The Logitech Control Center hosed OSX and was a piece of junk. From now on, I'm going to rely on the Apple native drivers to run my keyboard and mouse. What I appreciate about OSX is that its practically crash-proof. If you run compatible software on it, you will never have a problem. And I intend to see to it I don't have one in the future.
