I would think that clicking the Delete button in my inbox, thereby vanquishing a number of entries, would also refresh the "Inbox(X)" listing in the "Post - Reading Page - Inbox - Account - Invite a Friend - Help" navigation at the top.
Instead, after I clicked Delete and the entries went away, I had to refresh the page to get the Inbox number to reset.
