OP
Same thing happened to me sometime ago. Wer you playing the Diablo 09 priv server? (thats what did it for me). Response from devs/blue on the blizzard forums was basically:
"Looks like you were playing on some illegal servers. We've seen this before, and am not sure how to correct. We highly recommend a fresh install and deleting the character and removing all 3rd party programs, as they will jeopardize your account."
You will have to delete the character (if you want to use the same name), and I recommend reinstalling, as I'm sure you're cube showed the Plugy cube size, which is actually why it happens (game tries to squeeze item into a full cube oin bnet, but glitches into getting stuck on ur cursor I guess because the game also catches the plugy cube size too.
The Blizzard support really isnt much help, huh?
