I am a fairly new mac user. I have had my mac since september and it works great but for some reason my downloads are disappearing on me all o fthe sudden and I do not know what has happened. When I download a file normally, the download box opens up showing me the file and what % the download is at. However, now the box is completely empty. I know I am downloading files though because the website says i am downloading a file AND the bottom of the download box says "3 downloads" but they are nowhere to be found. When i look for them in the downloads folder in my finder, there is a file with a "safari logo' but when i click on it, it just brings be back to the empty downloads box. What do i do ??? PLEASE HELP.
