Hi, I'm not very good with computers, so when something goes wrong I have no idea how to fix my mac =( Today, for no reason I can understand, my drag and drop function stopped working. I can't drag things (applications, documents, images) to/from the trash. I can't drag images from websites and drop them in folders on my desktop. I can't drag songs from iTunes. I can't drag things from one side of my desktop to the other. I select them, and then they just won't move. This feature was working fine yesterday. What have I done?? Yesterday, I was deleting a few programs I don't use, GarageSale, iPhoto, DiskStudio (I don't even know what that is >.<). Could I have accidentally deleted the drag function? I use OSX 10.5, and my computer is a 2GHz Macbook. =( I'm really hoping this is reversible. Thanks, Lex.
