dragging an calendar item to deleted folder does not trigger ItemRemove event

[Jason]

On Outlook 2003, when dragging and dropping an calendar item to the Deleted
folder, the ItemRemove event is only fired on one dev machine, not on other
machines (VM, non-VM, pop3, exchange). There are other appointments in the
calendar folder, even same day. Deleting through Delete button or open then
delete do trigger the event.

Why is that? Any workaround?

The problem was gone by itself after a couple of builds. Strange but I am
relieved.
