[AccessD] Calendar Control Not Displaying Day Numbers

I'd check the Windows International and Regional settings first, but
honestly... I can't see how that would affect the actual day's number.

I have one user who reports that his calendar control, while it displays, is
lacking the numbers for the days. That is (trying to explain this ... ), the
calendar control displays, with the proper days in the boxes, etc., and if
you click on a "day", it does return the proper date.

Any ideas on how to troubleshoot this?
