It looks like this is a bug in Quicken 2007: When I move arrow up/down, or page up/down keys cross to another month in Quicken Calendar (Ctrl-k), I found there is no text updated in the header to reflect the current month. This will cause confusion for which month the calendar is currently displayed. I have Quicken 2004. This version will update the header when calendar moves to another month.
Hope Intuit can fix this bug.
