I don't know what is going wrong with my Lion.
I downloaded a couple of MP3 files a few hours ago, they go to the Downloads folder, I don't know why, on the KIND column is showing them as Document and not MP3, this is one problem, but the badest one is when I select them, hit Command + c and go to my Desktop and hit command + v, it copies the files but in few seconds it deletes them, like if I had not copied them.
what is going on ? did Apple change the way where I should copy my files ?
Why are they tagged as Document ? why do they vanish after the paste ?
when I try just to drag them, they go normally, but if I try to copy them, they won't go, ie: I move them to the desktop, hit command + c and try to paste in any other folder, they won't GO !!!!!
