Timedatepicker control

I am using a Timedatepicker control displaying TIME ONLY in an Outlook form. The UpDown property is set to "true" and works fine. However, if a user clicks in the control and manually types a single-digit HOUR the control beeps and reverts back to the original value. If the user types a double digit hour, it changes the value. If the user types in, say 2:00 as 14:00 it accepts the change. How can I get the dtpicker to accept a typed-in value as well as a up/down value?:dunno
