Strange Issue on Restore Application Process

All,
I have a strange issue with being able to restore an application from a previous date.
When I choose File>Restore Application and it suppose to show all the applications so I can select an older version.
The applications are not all there…
I have been specifically working on a application for almost 2 weeks and I wanted to restore an earlier version and it is not in the drop down list.
Now this is a LARGE project in my list of projects I have, but this is an application that should be there…
Does anyone know where these applications are strored in the database and if there is a maximum number of applications it will show in the drop down list?

ANY Help appreciated as I cant restore an app I need to get to…

Thanks

Kevin

Have you renamed it?

Nope… this is not good to happen
if I am working on it now and it still isn?t in the restore… that makes no sense
