Did you experiencee this on your machines also? When I use the brightness, volume, mute buttons, my X freezes for 2-5 seconds totally. Mouse pointer stands, then the matching symbol (volume etc) is displayed. This is NOT the symptom of overload (spinning beachball), and does not happen on every systemstart. Any ideas?

OS X.2.8, G3 400/500

This happens as well on my iBook, although the delay is much shorter - usually only a couple seconds or less. I think changing brightness and volume are more processor intensive than you would think which would explain the lag on your G3. I remember using a DP G5 at the Apple Store and OS X seemed to react much more quickly when I pressed the volume or brightness buttons.

BTW I have an iBook 1.2 G4.

I have noticed that kind of behaviour but only when I first do it. If I'm watching a movie on my 700 G3 ibook, it lags changing volume etc. once but after that it's fine.

It would be better if OS X reserved resources for these things as it wouldn't use much really but then if you're not using it, I guess it might be a waste.

I actually get some hard drive thrashing when I press the caps lock, maybe the same deal. Just need a faster system or more Ram.

Ditto. I get it on my TiBook 500 when it's the first adjustment made in a while - seems like a cache-related issue.

Yes, well known problem. Train yourself to tap the keys repeatedly instead of holding them down.

No. As I wrote, this happens only every 10th or 20th systemstart, no matter how many/few programs are used! It could be connected o the uptime.
Observation - as I just upgraded to 10.3 I noticed similar quirks on the very first startups - no dimming possible, no sound confirmation on volume change (w/ option checked) - these problems went away though. Seems to be a larger Apple problem connected to the keyboard controller?

That's right - usually (95%) the systems acts like that! But my 10.2 freeze was way beyond that.

This makes no difference performance or freezing wise! In case the machine has its mood, the freezing occurs then multible times, once for every tap!!!

But as I said, I'm now on 10.3, I hope this very problem is gone on Panther.

There's no change in Panther to this behaviour.

Again, are we talking about the SAME??? I am not talking about a small hiccup (cache, whatever related) to load the fading display icons. I am talking about an up to 5 seconds FREEZE of the whole system EVERYTIME I change volume or brightness. Like OS9. Mmmkay?

And yes, since upgrading to 10.3, I have not seen this again!

Putting up with such a freeze is absolutely ridiculous. I have never seen such a thing occur in any version of the OS, so it sounds like it was a problem with your installation. Happy to hear that it was cured by Panther. How long did you put up with that behavior?

As I wrote, that only happened every 10th to 20th startup, so I didn't occur that often. First time maybe a year ago - could be related to the last Jaguar updates, now that I think of it...

I had this with my Rev. A. 17" PowerBook. Especially when playing movies (and that's when I neeeded it the most). It would continue to play the movie, but the reaction to the button-pressing would be delayed forever and I couldn't do anything else with the computer. I upgraded the RAM and haven't seen the problem since.
