In Norton Security Suite > tasks > "Run Startup Manager" there is an option to "Delay Start" of the applications which normally launch when the computer turns on.
I read the Help page on this topic, but the description does not say how long the delay is or whether you have to later manually start these applications.
If the only way to start the applications I've chosen to delay is to open the Norton Startup Manager dialog, and click the link for "Run Delayed Items Now", then I would like to request the feature whereby the delayed items start themselves gradually after a configurable time period (eg: 1 to 10 minutes).
