Exactly same issue, was unable to change protocol association in WIndows settings. After wasting 2 hours of my time, i ended up configuring Firefox (Options/Applications/ magnet), but Shareaza still steals magnet association on the OS level (Win. 10 in my case), even magnet association is unchecked in Shareaza settings. Hope this bug will be fixed in Shareaza.
