Strange. Is this file hosted or simply local on your laptop? If local on the laptop I find it difficult to understand why it would be different when you got home.Edit: if you were away from home and working on a hosted file then opened the same file on your laptop locally changes made on the hosted file would not show up on your laptop until you pulled the file from the server to your laptop.
It's local on my laptop. It is the strangest thing I've ever had happen with Filemaker. The only thing I can imagine is that the file was open on my laptop overnight while my syncing program ran to back up everything, and somehow as I worked throughout the day, it was working on a ghost file of some sort.
Now, to start over....
