VideoStudio :: Save Location During DVD Authoring Process

In making movies I sometimes need to pause the DVD authoring process (Share, create DVD, with various clips in the timeline), and be able to pickup the procedure from the point of pause later. Not infrequently, after I've shut down the computer and restarted after a day or more. If I close the process, there's a message box displayed that says "saving project" but it doesn't say where nor give the opportunity for specifying a file name.

If the authoring process is re-started without computer or program shutdown and no intervening different work, the authoring process re-starts where it left off. But if there's a shutdown or diversion to other work, getting back the paused activity seems to be a lost cause: in the opening authoring panel there doesn't seem to be a 'get saved project' option available despite the various add video files/project files/other media buttons'

So, I set up a special test file with a unique name, made sure all the preference boxes pointed to the same working file space and did a sample run, closing the author process before getting to the burn stage. The save project file box appeared briefly. But . . . one cannot find the saved file in the locations specified by the preference boxes either in the main menu or the author panel preferences icon. And even if it was found, re-loading it seems to be a problem (see remark above)

This situation exists in VS11+ and also in VS14, so it seems to have existed for some time.

So, the questions:
1. under what name does the author panel save a partially completed work?
2. where does it save it?
3. how does one re-load a saved, partially authored work?
