Hi, I recently purchased a macbook pro os x lion and it's my first apple computer that I own so I don't know that much about how everything works. Since yesterday, I noticed that I can't move files in my documents (e.g. word, excel etc.) into the trash. When I try to, it asks for my password and deletes it but the trash icon doesn't fill up and the file gets deleted before I manually go into the trash icon on the dock to empty it, which is what I want. Does anyone know the solution to this problem? I'm really scared about making changes to the computer since I'm don't really know how macs work yet! :S Please help me! Thanks in advance.
