I have an existing project that I want to use as the layout for a new project (so I can keep track names, plugins, prochannel settings, etc).  I did a CTRL-A and deleted all the tracks/clips, then deleted any automation envelopes that were there. I "save as" with a new name, but the project end point from the old project persists. It thinks I have a project with 182 measures (which the old project was). How do I get it to behave like a new, empty project? What am I missing?
