I'm thinking, with the download counter, if you want to increase the popularity of your download, go click on it a couple hundred times, walah, your file has been downloaded a few hundred times... or so it seems...
IMO this is a bug, I mean, some people would use the download counter to track popularity of a file, and by increasing it just for it being downloaded can lead to non-correct information...
Perhaps we need a way to track if the file has been downloaded by a certain user/ip before?
My example, look at my dl count of my attached file.
