These options only apply to WinCalendar when running in Word (Called from Word)...
1) Enable WinCalendar within Word: If set to off WinCalendar will not be loaded in Word & the WinCalendar menu options will not be available. You will need to restart Word for this to take effect.
2) Default Calendar Date Value: When 'Always today date' is selected WinCalendar does not remember the last selected date in the Word Session.
3) Double-Click instead of Single-Click to select and insert a date: If checked, WinCalendar will ignore single clicks.
4) Show WinCalendar in a separate WinCalendar Menu: If the second option is selected no WinCalendar menu will be shown... WinCalendar commands will be available from the Word Tools menu.
