Thanks Howard for letting us know. I had it happen yesterday — lost some layout changes while working in 13.
I was working on my office LAN, hosting by FMS 12, clients FMPA 13 and FM Go 12. I created a quick-and-dirty table in a child file to do some data hygiene, since dirty data happens, esp. in a client-developed database that's been in use since 1996. I built the table, amused to discover that the FMPA 13 layout wizard puts you in Modify Table View to create the table. Cleaned up some data, went on to something else. Later returned to the table - what the heck, it has no fields! Where did they go?! Hurried on, rebuilt it, scratching my head, but marching on with the To Do list.
My solution is not young - the client must have developed it in FM 2 or 3. I consolidated 3 files into a single file, and am adding a Go interface and other new functionality. How old are the solutions where you've had this problem? I'm looking for commonalities.

Yup, I'd thought about file age after your post. The one last month was older (I think FM 8.5), but the one with the problem last week was built entirely in 13.
