>I have the textbox's Century property set to "Default", the form oSessionEnvironment.cCentury set to (None), and the aGlobalEnvironment.cSessionEnvironment.cCentury set to "OFF" and all dates in Grid column has a 4 digit year.

Hmmm...it sounds like you're doing everything right! Check out the sample Project Manager application's Projects form...it has two date fields on its page 1 grid. Maybe that will help you narrow it down. You may also want to put in a breakpoint and make sure that CENTURY is truly OFF in your form's session.
