If a user is editing a form in Microsoft Dynamics CRM 4.0 and uses the shortcut keys (for example ctrl-s to save the record), then the OnChange event for the current field is not fired.
Therefore if the user has modified the value of the current field but not yet stepped off of it, then any custom logic in the OnChange event will not be executed.
