input mask lost when default value is used

[Josep B]

Hello !

I'm using a control for intruducing dates with a short date mask
__/__/__
so far so good, the problem arises when using a default value date()or
now() for the control, then I lose the separators __/__/__ when
writing a different date.
Even using format(date,"dd/mm/yyyy") I get the same result
I've seen this problem previously reported but not solution worked for
me.
Acess 2000 is used

Thanks in advance
