I just switched to IE9 and I like it. I notice that when I open certain files, (MP3, WAV), my computer now uses Quicktime rather than Windows Media Player. I tried disabling Quicktime, but when I do, the files won't open at all. These are files, (MP3 and WAV), that I used to always open (and would like to continue to open!) with Windows Media Player. I can't seem to find how to make IE use Windows Media Player. Any helpful ideas?
