All-day Events view

I have 15 All-day events updated on my "shared" Calendar.
I can only see 12 items listed When I use the preview. I
have myself set-up as the "author" and and have given
three other user's Read, Write & Edit capabilities. When
they view my Calendar they can only see 8 items listed.

The only way I have found to view "all" of the All-day
events updated was to use Print Preview.

Is there another way, or is there some default or system
restraints limiting the "view" of All-day events?

Why would "my" view be different then those I have
given "rights" to my Calendar?

Any input of assistance would be greatly appreciated.
