Droplet for How Long an App has been Running

The Robservatory blog featured a method for finding out how long an app has been running. Here’s the source for an AppleScript application that lets you drag and drop your running app’s icon to see that information. Put this script into an AppleScript Editor (currently known as “Script Editor“) document, then save it as an application. Don’t copy the line numbers. Be sure your app is running, then drag that app’s icon onto the new app you created.

Warning: If the running process of the app doesn’t have the same name as the app’s icon (excluding the “.app” extension, of course), the droplet won’t work.

Previously, I discovered a problem with some apps with longer names, and provided a revised version. Now I’ve added the ability to select an app icon in the Finder and launch this app from the Dock or the Script menu for those of you who might prefer not to drag your app icons.

	my build_answer(the_item)
