How do I change an Application Icon in the Applications Folder? I just installed an application and drag/dropped the file into the Applications folder. The application (or folder) icon is showing as some grayed out icon with a crossed-out circle over it in the Applications folder's stack in the Dock. This is not the application icon obviously. When I go to the Application Folder it displays correctly. 

How do I make it display correctly in the Application Folder stack in the Dock? Is there a way to refresh it somehow?
Is is a normal behavior for downloaded applications.

After having started the application one time and accepted to open it - log out and back in.
