It seems that the software is currently only saving Analysis for the current working zone. If you have Key Images outside of the working zone they will not be saved.
This is an issue for my workflow, where I run through a hockey game and select moments in the game that I want to analyze in a general sense. I will then go back through the video and specifically analyze smaller moments within those key areas. If I save my analysis while I have a working zone selected then I lose all of my other Key Images, etc.
This could be WAD, but it is a real pitfall.
Perhaps a "save all" and "save working zone" checkbox is required? I can see how both may be useful, but I just lost about an hours worth of work by "saving" after I analyzed one specific event.
