I am using a prev. gen (1.5ghz AL 15") powerbook and I have always noticed quite a bit of delay when using my keyboard controls for volume. What I mean by this is as follows: When I go to "up" the volume, I press F5, which does nothing for about half a sec, and then the on screen white visual controls come up. If I release the F5 button, the second I see the onscreen visual, the volume "meter" on the screen continues to increase even though I have let go of the key. Same for F4 (decrease) Does anyone else see this kind of delay? My sister's 1ghz powerbook does not behave this way despite my computer being much faster + more ram + Tiger, etc. etc. Any idea what would cause this?
