Are you forgetting about the other applications that I may be running at the time? My system idles at almost 2gigs used.
You say I have "NO REASON" to ever do that? Batch processing.
Items can be images, video, whatever.
Using photoshop by opening up 200 images and then processing with the "actions" panel is not "batch processing"
I'm not on a high horse. You give poor information that needed to be cleared up, and the last thing we need around here is more mis-informed people.
