Help? I'm still a newbie and I think I messed something up. When I booted my iMac this morning it took longer and with lots of scratching on the harddisk. And then I noticed when I mouse over the dock the icons don't magnify or jump when I click on them. I checked the preferences and both the magnification and the animate opening applications are ticked. The only thing I did last night was following this tip: http://osxdaily.com/2007/05/17/make-hidden-applications-transparent-in-the-dock/ I guess I should know better than muck around with terminal when I don't really know what I'm doing. I have since undone that and the icons don't get transparent when I hide an application. But my dock is still not working properly. Is there a way to reset it? Can it be restored with Time Machine? Anyone know how to fix that?
