Mouse, keyboard issues; 8 core MP; 10.5.2

Question

My dad just bought an 8 core Mac Pro. He only had it a few days with 10.5.1. But after applying 10.5.2, he and I have both experienced issues with the numeric keypad being unresponsive, as well as function keys to which we have assigned Quickkeys triggers. Pressing, F1 on the new slim keyboard, for instance, does not trigger the quickey, but attaching his old keyboard does. That sounds like a keyboard issue, but there is more.
Similarly, double clicks from his mouse will not be recognized (Apple mighty mouse). The finder appears to freeze, and we generally have to resort to relaunching the finder to regain control. Very strange behavior.

Answer 1

Hi, how's about a Pram reset, it's harmless, non-intrusive and can only help. Directions:
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.
Try this, and if it fails to correct issue, boot in safe mode, with the shift key held until start-up.
Post back with results, also run Disk Permissions. It's in your Utilities folder>Disk Utilities. Also, boot off the install disk while holding the c key, press English and go to Utilities and repair hard drive.
These three simple procedures may solve many issues.
