hey guys.. Since the past few days there has been this strange problem. Any type of file be it a movie, a song or a .dmg file... all of them seem to open with Excel 2004. I changed the default application for opening these files. It works perfect with old files, but when I download new files.. all of them seem to open with Excel again. And it seems to use some strange icon..I am attaching a screenshot with this post. What can be the problem here?
