Antonio,

I have found that AddItem and AddListItem have undocumented behaviour which is said by MS to be "by design".

My solution is to use the List property exclusively. Yes, I give up the ability to have an nItemID for any item, but that turns out to be an advantage if you plan on deleting items from the list. This is because RemoveItem does *NOT* maintain the nItemID "table", leaving it as-is, so if you later try to "add" an nItemID which was already previously added (then RemoveItem()ed), it will invariable go where the old item was regardless of where you WANT it to go.

Just thought you should know,
Jim N
