I have uploaded two short audio clips, not more than :03 total. I have created numerous bins but have only uploaded jpgs to two of the bins, using the command rather than dragging media in. After creating the 1st 2 bins, I saved and closed just to be sure the project would re-open. It did so I continued to created numerous other bins but did not add media to them. Periodically I would save the project. After completing naming all bins and saving, I closed the program then re-opened it. As soon as I selected the project to open, I got the "not responding" message. It has been at least :30 and still no response.
The Task Manager also says "File I/O surrogate (not visible).
