I'm running Mozilla Calendar 2004040813 on Firefox, and it is displaying
duplicate and incorrect (on wrong days) entries.   It happens most when the
calendar is first drawn or the month is switched.

Reproducible: Always
Steps to Reproduce:
1.Enter some events   (Or load a holiday list)
2.Switch months
3.

Actual Results:  
Incorrect and duplicate entries

Expected Results:  
correct and no duplicate entries.

The .icf file seems fine.  It appears that Calendar is interpreting or
displaying the information incorrectly.

If you're seeing this for events happening on daylight saving time changes only,
this is a duplicate of bug 167886

No, it's not just Daylight Savings.
Note:  This only occurs with Firefox nightly builds.   Mozilla 1.7RC1 and
nightly builds work fine with the calendar 040408 version, as does Firefox 0.8

This is a Problem with 1.8a! I switched back tu 1.7 RC2 and everything is fine
again. It does not only show duplicats, but also as you can see in the
attachmanet of Comment #1 in the Events-list all entrys are "false". The Same
with the Todo list.

This also happens when moving and copying events. I've been seeing this from
time to time, with every calender build I tried, and combined with firefox 0.7,
0.8, 0.9 or thunderbird 0.5, 0.6 and 0.7. This is what makes Calendar virtually
impossible to use. Only restarting ff/tb works, but only until I create new
events and switch months or copy/move events.

It seems to occur when you change the recurrence field to annual. I was doing
this for birthdays and it kept entering the birthday twice but on different
dates next to each other.  I notice that Daylight savings has the same problem
even though that is input by the computer itself.
