I'm not setting the date in the control at all. I use the form to pick a date and let the control default for the initial date. I am using a CodeBook 6.1 modal form class with the MonthView used to select a date to be returnded by the form.

When I click on either of the MonthView buttons to move forward or back a month or when I click on a visible date falling outside the current month, I then get the error. I can click around within the current month, I just can't go outside the current month.

I think I noticed in one of the other refrences to this problem that the error does not happen when the control is on a form, only when it is on a form class.
