OK, this keeps getting weirder. Preview app was NOT running. I double-clicked on a PDF on my desktop. The PDF opened with the Preview app and the icon of the Preview app appeared in the Dock. I closed the PDF and the Preview app stayed in the Dock, but as soon as I clicked on some empty space on my desktop, switching from Preview being active to the Finder being active, the Preview app disappeared from the Dock. All of this was only a few seconds after first starting up the Preview app, so it's not like it was "suddenly terminated" due to being unused for a long time (and my Mac Pro has plenty of memory and nothing much running). Is this the expected behavior under Lion? I don't want to make Preview a permanent resident in the Dock, and yet I want its icon to be there when its running, so that I know it's running. Is this a bug or just the new way of doing things?
