okay let me start by saying i know how to solve my problem, i just dont know why it happens.. here we go. i just installed vlc player from a downloadable disk image. then after installing it i threw away the .dmg file. I have not ejected the disk image and i know this is why i cant throw it away... the thing i cant figure out is when i try to empty the trash i get the message "The operation can't be completed because the item "vlc-1.0.3.dmg" is in use." Then it prompts me to either stop or continue. No matter which option i click, the trash does not empty. Nothing happens. What are these two options supposed to do? ive always wondered... sorry if this post was confusing.
