After I've downloaded an application from the Internet and dragged it into my Applications folder it is shown with a "prohibited" crossed out circle icon. When I click on it the first time I get a popup dialog confirming that I want to run this program that was downloaded from the web.
That's all well and good, but even after I click OK the icon still is stuck like this until I log out and/or reboot the system. Is there any way to get it to display the application's real icon without rebooting?
