Hi,

I have a MaskedEdit  on a textbox to input only numbers. It works fine with the new IE and Firefox. However, it say invalid data when I enter a two or one digit number in the older Firefox V 1.0.1

Here is what happen, the mask only allows to enter upto 3 digits. So if I enter, 2 or 1 digit in the textbox will display:   _12   or __8 . I think the problem is that it reads  the underscore as a number. Therefore it's not valid. So how to get rid of the underscore in the mask? or is that any quick fix to this?  Thank you
