The only thing I can think of is to unbind the textbox on GotFocus, and re-bind it on LostFocus.

IOW, save the txt.ControlSource to txt.oControlSource, and txt.Value = DTOC(EVAL(txt.oControlSource)). On the way out, after you verify the date value, reset the txt.ControlSource and set the txt.Value = ldMyNewDateValue.

Caveat: untested....
