Hmmm ---
OK, that's pretty weird. Do you have any parent class code that may affect the Format or InputMask properties? Try running the Class Browser, open up the form, and do a View Code (save it as a separate file). See if there is anything unusual there. Also, are you running a Private Datasession or the default (public)? Any further information you could provide.....
