Use 10.2 force quit dialog to confirm app lockups System
I don't know how important this is, but in 10.2 when you bring up the force quit dialog box, if an application is not responding, it is listed in red. I guess this helps to tell the difference between an app that is just processing, and one that is actually hung.

[Editor's note: Be slightly cautious using this visual guidance as the decision to force-quit an app. I've had the Finder show up in red when it was trying to access an iBook I had put to sleep (whoops!); it returned to its normal color after I opened the lid on the iBook. Still, it's a nice visual indication that the app you think is hung up is truly hung up.]

Easier way

Its much easier to ctrl-click the icon in the doc - if it is not responding, it will say "Application Not Responding" at the top of the menu that pops up.

Easier way

I agree with this easier way, although let me note that this is significantly improved in Jaguar.

In 10.1, if the application wasn't responding, you had to wait a while before the dock menu would be displayed.

In Jaguar, if the application isn't responding, the menu comes up right away and force quit is immediately available (no option key needed)

Finder blocking
Authored by: ajmas on Sep 13, '02 11:15:13AM

If the Finder was blocking when trying to access an off-line server then this would be an indicatation of a design error. Surely only the windows representing access to the off-line server should be blocked, at least this would be the case if each window was assigned its own thread.

Seeing that it's not responding doesn't really give extra information
Authored by: landtuna on Sep 13, '02 03:25:10PM

Seeing that it's "not responding" doesn't really tell you anything. The system is probably just using a timer since an application has responded to an event or signal to decide whether it's "not responding." While busy computing things, if the application isn't threaded well, it might not respond but then come back later.

I don't think there's really any way of knowing if an application is hung up except by looking at how it's acting.

Exactly -- computer scientists know this as "The Halting Problem", proven in the 1930's by mathematician Kurt Gödel and computer scientist Alan Turing . If you're curious, here's the best site I've read on the topic (requires a basic level of programming experience for best consumption): http://www.cs.washington.edu/homes/csk/halt.html [link will open in new window]. --Krishen
