Hi,
I've started using Orage recently and I'm very satisfied of it. However, I think I found a bug : whenever you set up an full-day event using the DURATION property, the event is actually shown in the calendar for one extra day. If DURATION is not used and both DTSTART and DEND are given, then the event is shown for the appropriate number of days.

Reproducible: Always

Steps to Reproduce:
1. Create a new event and make it "Full-day"
2. Assign a duration of X days, don't assign and end date (this is default if the event is created within the Orage dialog)
Actual Results:  
Observe that the event is actually show for X+1 days in the Orage calendar (other iCal compliant programs show the event correctly lasting for X days)

Expected Results:  
The event should be shown in the Orange calendar as lasting for X days

I mark the problem as Major since I think it can easily misguide people using this otherwise excellent program. Especially if one's sharing their calendar with someone else. Otherwise, I suppose it should marked "Normal".
