Click and Drag/Copy and Paste will not work

[kevin.sonoff]

Greetings-

Yesterday, I went to install a typical Mac OS update using software updater only this time when it completed my click-drag and copy-paste functions stopped working. Can anyone help solve this? Here is what I have tried... restarted (multiple times), tried booting up in Safe Mode (by pressing shift when starting up), and repaired disk permissions using disk utility. I even ran all of the daily, weekly and monthly scripts using Cocktail. I'm stumped. Any suggestions?

Thanks,

Kevin

My system: Macbook 2.4 GHz Intel Core 2 Duo, Mac OS X (10.5.7) 2GB of Ram, 160GB HD
