So I thought I would empty my trash using the "Secure Empty Trash". I didn't have that much in there, but it seemed to be taking forever, so I checked up, and noticed it said there were thousands of items to go. I stopped it and went to check that everything was okay. That's when I remembered that while using a folder I kept in Library (under my user account, so as to be secure from my roomate's snooping when he uses my machine with his account), I accidentally pulled the library itself on to the desktop when I meant to pull the windo up a bit. So now I had this Library icon, and I didn't know what to do with it. I didn't want to erase it ( ), so I tried to drag it onto the hard drive. When I did, a message popped up telling me that I already had it there, and did I want to replace the one I had? I said no, and dropped it into the trash. After stopping trash from rewriting everything, I opened the library folder, and found it much lighter than it was before. Now all that's there is icons, documentation, cookies, caches, safari, syndication, preferences, and itunes. Also, since doing this, safari is not displaying everything properly- here on macrumors, avatars are not showing up and my quotation marks above are right on top of the letters. On some pages, text and pics are right on top of each other. WHAT HAVE I DONE?
