Set the view menu to check the 'week' item. click 'Monday, and you will see
the check in the all day checkbox. Click edit menu, Delete. Now click any
hour of Monday, and note the checkbox for all day does not appear as
checked.
Mark, this worked while I was in the week view, but when I switch to the
month view (I use month as my default view.) I still get the all day box
checked. Is there a trick that gets the all day default in month view?
