hello I have an Ibook running 10.3.9 and I have 2 alias icons in the dock and cannot remove them. I tried to click and drag them nothing......... I click/and hold and only a window appears for finder but not a way to delete the alias icon. I ran file find and the programs have been deleted already its firefox browser icons. so when I search hard drive nothing no files no refference to firefox so these icons are like like stuck there with no means to remove/delete or anything
