Game Mechanics: Successful(?) beg with item on cursor

[Jimjam]

When I beg from an NPC while I have an item on my cursor I get in my tell window '[NPCname] is not online at this time.'
and in my general window '[NPCname] is interested in making a trade.'
These events cause the fail message 'Your attempt at begging was unsuccessful.' to also appear.

I have no idea whether or not beg should work with an item on cursor, but it would be nice for there to be an error message explaining why the beg was unsuccessful?
