I have a problem with the stack function in leopard, the applications stack in particular. Here's the problem
The icon beside the perfectly fine safari icon is what shows for every new application I download. Looking at the application in the finder window shows the correct icon and even in the dock it looks fine, it just looks like this in the stack. The application works fine and as far as I'm aware its meant to be ran under leopard. It does this with every new application I have downloaded so far with exception of a couple.
My Airport utility also had this icon, but unlike the problem above it looked like that all the time finder, dock anywhere and it wouldn't open (I had to download a new copy from the apple website to fix.) I have no idea whats going wrong there seems to be a load of these white no entry signs cropping up here and there, and repairing permissions and restarting does nothing.
