I enter months worth of Single Day-Long events into my Outlook 2003 Calandar
(eg. Meeting with John, Labor Day- No Work, etc...).  After everything is
entered perfectly I close my outlook down and I open Outlook again, randomly,
everything I entered (those single day, simple All Day entries) change.  

For Example, for a "Doctors Appointment" on 7/12, the appointment will
stretch two days (7/12-7/13) and have a black little clock on the left and
right side of the event.  This happens to every single entry I enter into my
calandar.  So, instead of having a calandar full of single day events, which
I want, I have a calandar full of two day events forcing me to go back
through each one and adjust the dates.  How do I fix this?  What are the
little black clock things?

Any guidance you could give would be fantastic!  Many thanks for your time.
