Google Chrome app file opened is not always in front, receiving focus

On Windows Vista, I'm launching files associated with a Google Chrome "Application Shortcut" app by double-clicking them. While they will always open this way, they will sometimes not receive focus -- i.e. they sit in the task bar quietly but don't actually show in front on the screen (until I click on the app in the task bar again).
