In the past I was able to drag folder icons (applications or documents, for example) into the Dock, where they appeared like the original icons. In Snow Leopard, the icons don’t display properly – instead they revert to generic ones. Is there a fix for this that will show the icons as they are?
The trick is to view these items as folders rather than stacks, which is easily done. Simply Control-click (or right-click) on a folder in the Dock and, from the menu that appears, select Folder in the Display As area. The distinctive folder icon should appear. The icon will remain, regardless of whether you choose to view the folder’s contents as a fan, grid, or list.
