It seems like I'm getting this error if nothing was entered in the date field. It it has date already, it doesn't give me an error and I'm able to go out of this field. However, when I set focus back, it shows 1900 as a year. I'm going to verify, if it's VFP native behavior or it's my date class showing this behavior.

Update. It is something peculiar to my own class. I'm going to dig in.

>>If a user types 0000 as a year in date fields, it converts automatically to 1900. Is it VFP native behavior? The user thinks, that it should display an invalid date message instead. What do you think? How can we make it generic?
