Response on changing screen brightness

[Dennis Fazio]

I'm curious if anyone else has noticed this phenonmenon.

I can use the function keys (F1 and F2) to decrease or increase the LCD 
screen brightness on my Aluminum PowerBook running Panther 10.3.3

However, if I hit the F1 or F2 button many times too rapidly, it would 
respond quickly for the first 4 or 5 steps and then slow down a great deal 
with the screen graphic fading and reappearing and the brightness increasing 
(or decreasing) one notch about every 5 or 10 seconds, become a very slow 
typeahead. This also affects the performance of the entire machine, which 
slows to a crawl until all the typeahead keypresses are complete.

I find that this is not consistent, and only works this way intermittently. I 
have not yet determined the conditions when it happens. But it is a real pain 
when it doe. Have others experienced this at all?
