Dock stack 'no entry' icons

[BeatMaster]

After using Snow Leopard for a week or so now I've noticed that everytime I drag-and-drop a new application into the applications folder on the dock the icon always appears with a 'no entry' sign overlay. Sometimes the proper icon is shown underneath (VirtualBox) othertimes it's a piece of paper with a paintbrush.

Only after "killall Dock" at the terminal will the icons refresh correctly or restarting the system.

Similarly when I download a file the stack icon doesn't update once it has completed.

Any help before I re-install and try again (running 10.6.3 with all updates)

Sadly this doesn't happen

Tried to have a look through the podcasts but couldn't find anything Quite a few to go through so could take some time. Had another search around and appears to be a common problem with no real fix as such.

Have found an interim solution for the time being using Automator. Create the following:

1) Folder Workflow
2) Change the folder to be Applications
3) Add a Run ShellScript action with:

xattr -d com.apple.quarantine
killall Dock

4. Save as New Application

Everytime a new application is added to the Applications folder, it will remove the quarantine attribute and reload the dock with the correct icon
