I was going nuts attempting to enter a date into a DATE field in a database I imported from dear old 6. I tried entering a new DATE field, I tried changing input and output settings. I created a couple of stock databases from templates containing DATE fields without touching the field properties, same result: I would type in mm/dd/yy, it would display, and I soon as I tabbed to another field it would vanish. The DATE data imported from 6 showed up with no problem, but nothing new. As I was careening around I noticed that “today”, “tomorrow”, and “yesterday” seemed to work just fine (as long as I didn’t have “input pattern” set to __/__/__), so I tried typing in a text abbreviation for the month: nov, dec, jan - and it worked. I got mm/dd/yy (numerically).
Is anyone else having this issue? I’m running a late 2016 MacBookPro with OS 10.12.6.
