Overflow error when opening form with MSCal.ocx in Access 2002

Our Access XP application uses calendar control(MSCAL.OCX).
It works fine on most machines, however some sites reported “Overflow” error(6) when they tried to open a form with a calendar.
It’s possibly related to problems, described in the articles http://support.microsoft.com/default.aspx?scid=kb%3ben-us%3b236529 or http://support.microsoft.com/default.aspx?scid=kb;en-us;Q311219


Our support team managed to workaround the problem by manually copy expected version of mscal.ocx instead of wrong one.
