I just got my first Mac two weeks ago and I'm still getting used to it. I installed Windows Media Player, but was told by many people to uninstall it. Last night I grabbed the entire WMP folder and dragged into the Trash bin. I followed the instructions in this Mac for dummies type of book that I have. However, when I tried to empty the Trash, it wouldn't allow me and it said that a number of files are "locked." I tried putting the entire WMP back to the Applications folder and then deleted it again. I then tried to empty the trash again and it still didn't work. Could you please advise me on how to get rid of the files in my Trash. Also, I can't send files using IM clients. I can't do it through Adium and it won't work through iChat. Last week, however, it worked fine with iChat. I got 10.4.8 now, but I started experiencing problems with sending files while I still had 10.4.7 Thanks.
