The expresions for properties are only evaluated when class is instantiated for the first time and stored in the cached copy of the class. All class instances are created from that cached copy. As result they all have the same value of such properties.

>For me it, is not evaluating datetime() when I save the class. It is doing it the first time I create the object. And then, interestingly, it is using the same time every time the object is created. Well, almost every time. Issuing a CLEAR ALL makes it start over with the correct time the next time the object is created. And so does exiting VFP and coming back in.
