[Gmail] folders

I've managed to get this working with Gmail, the INBOX anyway, but having some difficulty working with the folders. It would appear that the Sent, Trash, Draft, etc folders are all "subfolders" of [Gmail], try as I may, I cannot get this to work with Gmail, the folders anyway, thus no delete, or move. The folders show up, but there is no access to them, from what I read webmail plus does not work with subfolders, so this may be the issue....any help would be greatly appreciated...

thanks
