Adobe Reader Hijacks Preview as Safari's Default PDF Viewer
Installing the latest Adobe Reader causes Preview to be overwritten by Reader as the default PDF reader in Safari. There's a setting in Adobe Reader prefs that should aloow one to change the setting, but it is greyed out. Thanks Adobe! You'll need to go to your HD/Library/Internet Plug-in folder and remove the Adobe plug-ins. Quit and restart Safari, then Preview is default again.
