9700 running 6.0.0.448 with BES.

I've had this phone for a couple of months now, had a 9000 before that, and an 8800 before that. I've noticed that occasionally I create a new calendar entry, then find later that it's in the calendar twice. Same time and date, etc. I don't think I ever saw this on my previous phones.

It's not all the time, just occasionally. Has anyone else seen this behaviour?

I'm also regularly finding appointments moved to a later date than I expected. I often open a reminder and change the date to the next day by putting the cursor on the day and pressing the space bar. Perhaps this is just my space bar double clicking, but I saw one recently where it had moved several days ahead.

It just did it again. I created two test appointments, and I saw both come up once. I looked again a few minutes later, and one of them is duplicated.
