I've been running 2 versions of uTorrent successfully using desktop shortcut icons for 1.8.2 (old icon) and 2.2.1 (new icon).
Today I have edited 1.8.2 and the desktop icon has disappeared. It just leaves a blank icon shortcut which incidentally still works. I can pin the shortcut to the taskbar or start menu and the icon appears perfectly OK but I can't get the shortcut to show the (old) icon on the desktop.
