Why does Leopard display Address Book as an icon for Applications Folder? Why is one of Application icon broken?
Automatically Arranged By Name
The Application Folder automatically stacks up all Applications inside by their alphabetical order. Since our (my) Address Book ranks highest by its alphabetical order compare to others, it’s displayed as Application icon followed by others’ with no opacity, i.e. we can only see a little portion of others’.
The very same rule also applies for those folders located at the right part (launching part is the left part) of Dock.
Not An Application
Most of Applications are installed by dragging the installer icon into Applications Folder. The problem arises here. After the installation done, you will probably spot the broken icon of your newly installed Application.
This happens due to the fact that before you installed the Application, the icon hasn’t been defined and thus cannot be detected by Leopard. This can be fixed easily by dragging out and in the Application icon from Applications Folder.
