My secretary has been complaining about this. I noticed: Sometimes when selecting an appointment, the text in "Comment" box appeared for a second then disappears, it then re-appears after re-clicking that appointment. After updating an appointment, occasionally the text in "Comment" box was lost mysteriously. My secretary also complained about missing appointments. She swears she added that appointment and didn't delete it but it's just not there any more. Anyone else noticed anything like this?
