I'm seeing a bizarre issue with NSDatePicker in 10.11. First, I'm creating it programmatically in a Cocoa-AppleScript applet. If you're still reading: when incremented/decremented with a stepper, the time values never display a minutes digit with a 6 or a 9. For example, it displays 10:26 as 10: 2 and 10:29 as 10: 2, 10:36 as 10: 3 and 10:39 as 10: 3, and so on. I've tried adjusting the font size, frame width, etc, but I don't think that's the problem. Works fine 10.8-10.10.
Has anyone else seen this with a date picker used for time?
