When you have more than 10 contacts in an account and you scroll to the next page in the related lists (clicking the little arrow at the bottom of the contacts list) you see the additional contacts but you don't have a way to go back as the little scrolling arrows disappear.
This is very annoying as it then becomes necessary to load the account again, as even in the browser there is no way to go back to see the first 10 contacts.
Please check and confirm the bug.
