i'm using an "application shortcut" via chrome. i logged into my gmail account and then set up the shortcut through the chrome menu system. this put an icon on my desktop and it used the gmail fav icon that the browser displays. this icon is fugly. it's way too low res for use on my taskbar. so i found a better icon and changed the icon of the shortcut on the desktop. then i pinned the shortcut to the taskbar. for some reason, the icon is randomly returning to the cached fav icon version. any ideas why this is happening?
