When I right click/open with, and try to assign the correct program to open something, the list is apparently full and won't let me add another one. When I browsed for the program and double clicked it, it wasn't added and instead some entirely different program is set to open the file. (utorrent is set to open .ecm files WTF?) How can I find where this list is so I can delete it, or at least make it bigger?
