Limitations in DFilter script

There is a limitation in dFilter java script.
if the [B]input mask[/B] is like [B]00-92-321-XXX-XXXX[/B]
then one cannot enter the number that are in the input mask.
for example if the user will try to input 9, the box will display

00-92-321-9
again try to enter 9, it wont allow u 😮
the same is with the other number(characters) in the input mask. i.e 0,2,3 and 1

Solution will be highly appreciated. ?
