Deleting old FTP accounts

I've got a few ftp accounts in my smart ftp dropdown that I dont use any more but I've not managed to find any way of deleting the old ones that are not used now.

can some one help me out by telling me how i can stop them showing up in the dropdown list

Tools > Settings > History and select the one(s) you no longer want and delete them.
