I am glad someone can see my problem! but the gotfocus trick did not work. As soon as I enter a number the zero appears and does not disappear until I enter enough numbers (3) to reach the comma in the inputmask(999,999). This only happens once and only if I tab out of the textbox. if I go back to enter another number the entry works as expected. I think you are right, its a BUG! frustrating.
