Errors when deleting records using the new delete button

After deleting an individual contact using the Delete button on the Contact Summary page and then confirming the deletion, I got sent to the contact summary of the last viewed individual, which also displayed a message stating "You do not have the necessary permission to view this contact." The deletion still did take place, though. In other instances, I wound up at a blank page (when deleting an organization record.) Another time, I was brought to the Find Contacts page, with the same error as above at the top of the page. These problems do not occur when deleting from the drop down menu on the Find Contacts page.
