a few hours after downloading and installing this update my mouse stopped being able to click on anything.... however the mouse would still move around, and the cursor change to what it was supposed to be (eg. a hand on a webpage) but i couldn't click on anything... everything i could do from the keyboard worked fine though. even after 'relaunching' finder through the force quit menu i couldn't get clicks to work, and not knowing how to shutdown/restart just using the keyboard i had to turn the power off and on again, but kept having the same problem. after booting from the disc that came with my iMac, i the mouse would click on the installer, and after running a permission verify and then repair it came up without something in applications/utilities/airport utility and then something about contents but then the rest was cut off. after repairing permissions everything works fine again, and to be fair i did install the other updates (dvd player, imovie) that also came out today, but since the permissions errors were with airport utility maybe this update had something to do with my computer screwing up?
