I’ve been working on the database but changes I make do not seem to save. Why would that happen?
Please tell us more about the symptoms you are experiencing. What does “do not seem to save” mean?
The only reason I know of would be a permission error on your disk. Perhaps try moving the database into your main Documents folder.
I saw something today that might be pertinent. I opened a database and ran a couple of procedures that entered data into a record. When I closed the database it closed immediately, without asking if I wanted to save the changes. I opened it again, and the data that was entered by those procedures was missing.
I figured out that the reason for this was that the only changes made were done by those procedures, and I hadn’t made either of them undoable.
This is true - automatic save only kicks in if an Undo-able modification has been performed.
Based on previous correspondence I’ve had over time with the Ms. Stamp, I am fairly confident that is not the issue in her case (I don’t think she uses procedures at all).
